The CDT proposal 'Fuel Cells and their Fuels - Clean Power for the 21st Century' is a focused and structured programme to train >52 students within 9 years in basic principles of the subject and guide them in conducting their PhD theses. This initiative answers the need for developing the human resources well before the demand for trained and experienced engineering and scientific staff begins to strongly increase towards the end of this decade. Market introduction of fuel cell products is expected from 2015 and the requirement for effort in developing robust and cost effective products will grow in parallel with market entry. The consortium consists of the Universities of Birmingham (lead), Nottingham, Loughborough, Imperial College and University College of London. Ulster University is added as a partner in developing teaching modules. The six Centre directors and the 60+ supervisor group have an excellent background of scientific and teaching expertise and are well established in national and international projects and Fuel Cell, Hydrogen and other fuel processing research and development. The Centre programme consists of seven compulsory taught modules worth 70 credit points, covering the four basic introduction modules to Fuel Cell and Hydrogen technologies and one on Safety issues, plus two business-oriented modules which were designed according to suggestions from industry partners. Further - optional - modules worth 50 credits cover the more specialised aspects of Fuel Cell and fuel processing technologies, but also include socio-economic topics and further modules on business skills that are invaluable in preparing students for their careers in industry. The programme covers the following topics out of which the individual students will select their area of specialisation: - electrochemistry, modelling, catalysis; - materials and components for low temperature fuel cells (PEFC, 80 and 120 -130 degC), and for high temperature fuel cells (SOFC) operating at 500 to 800 degC; - design, components, optimisation and control for low and high temperature fuel cell systems; including direct use of hydrocarbons in fuel cells, fuel processing and handling of fuel impurities; integration of hydrogen systems including hybrid fuel-cell-battery and gas turbine systems; optimisation, control design and modelling; integration of renewable energies into energy systems using hydrogen as a stabilising vector; - hydrogen production from fossil fuels and carbon-neutral feedstock, biological processes, and by photochemistry; hydrogen storage, and purification; development of low and high temperature electrolysers; - analysis of degradation phenomena at various scales (nano-scale in functional layers up to systems level), including the development of accelerated testing procedures; - socio-economic and cross-cutting issues: public health, public acceptance, economics, market introduction; system studies on the benefits of FCH technologies to national and international energy supply. The training programme can build on the vast investments made by the participating universities in the past and facilitated by EPSRC, EU, industry and private funds. The laboratory infrastructure is up to date and fully enables the work of the student cohort. Industry funding is used to complement the EPSRC funding and add studentships on top of the envisaged 52 placements. The Centre will emphasise the importance of networking and exchange of information across the scientific and engineering field and thus interacts strongly with the EPSRC-SUPERGEN Hub in Fuel Cells and Hydrogen, thus integrating the other UK universities active in this research area, and also encourage exchanges with other European and international training initiatives. The modules will be accessible to professionals from the interacting industry in order to foster exchange of students with their peers in industry.

The first viable large scale fuel cell systems were the liquid electrolyte alkaline fuel cells developed by Francis Bacon. Until recently the entire space shuttle fleet was powered by such fuel cells. The main difficulties with these fuel cells surrounded the liquid electrolyte, which was difficult to immobilise and suffers from problems due to the formation of low solubility carbonate species. Subsequent material developments led to the introduction of proton-exchange membranes (PEMs e.g. Nafion(r)) and the development of the well-known PEMFC. Cost is a major inhibitor to commercial uptake of PEMFCs and is localised on 3 critical components: (1) Pt catalysts (loadings still high despite considerable R&D); (2) the PEMs; and (3) bipolar plate materials (there are few inexpensive materials which survive contact with Nafion, a superacid). Water balance within PEMFCs is difficult to optimise due to electro-osmotic drag. Finally, PEM-based direct methanol fuel cells (DMFCs) exhibit reduced performances due to migration of methanol to the cathode (voltage losses and wasted fuel).Recent advances in materials science and chemistry has allowed the production of membrane materials and ionomers which would allow the development of the alkaline-equivalent to PEMs. The application of these alkaline anion-exchange membranes (AAEMs) promises a quantum leap in fuel cell viability. The applicant team contains the world-leaders in the development of this innovative technology. Such fuel cells (conduction of OH- anions rather than protons) offer a number of significant advantages:(1) Catalysis of fuel cell reactions is faster under alkaline conditions than acidic conditions - indeed non-platinum catalysts perform very favourably in this environment e.g. Ag for oxygen reduction.(2) Many more materials show corrosion resistance in alkaline than in acid environments. This increases the number and chemistry of materials which can be used (including cheap, easy stamped and thin metal bipolar plate materials).(3) Non-fluorinated ionomers are feasible and promise significant membrane cost reductions.(4) Water and ionic transport within the OH-anion conducting electrolytes is favourable electroosmotic drag transports water away from the cathode (preventing flooding on the cathode, a major issue with PEMFCs and DMFCs). This process also mitigates the 'crossover' problem in DMFCs.This research programme involves the development of a suite of materials and technology necessary to implement the alkaline polymer electrolyte membrane fuel cells (APEMFC). This research will be performed by a consortium of world leading materials scientists, chemists and engineers, based at Imperial College London, Cranfield University, University of Newcastle and the University of Surrey. This team, which represents one of the best that can be assembled to undertake such research, embodies a multiscale understanding on experimental and theoretical levels of all aspects of fuel cell systems, from fundamental electrocatalysis to the stack level, including diagnostic approaches to assess those systems. The research groups have already explored some aspects of APEMFCs and this project will undertake the development of each aspect of the new technology in an integrated, multi-pronged approach whilst communicating their ongoing results to the members of a club of relevant industrial partners. The extensive opportunities for discipline hopping and international-level collaborations will be fully embraced. The overall aim is to develop membrane materials, catalysts and ionomers for APEMFCs and to construct and operate such fuel cells utilising platinum-free electrocatalysts. The proposed programme of work is adventurous: however, risks have been carefully assessed alongside suitable mitigation strategies (the high risk components promise high returns but have few dependencies). Success will lead to the U.K. pioneering a new class of clean energy conversion technology.

This Industrial Doctoral Centre (IDC) addresses a national need by building on the strengths of the existing EngD in Micro- and NanoMaterials and Technologies (MiNMaT) and the University of Surrey's excellent track record of working with industry to provide a challenging, innovative and transformative research environment in materials science and engineering. Following the proven existing pattern, each research engineer (RE) will undertake their research with their sponsor at their sponsor's premises. The commitment of potential sponsors is demonstrated in the significant number of accompanying letters of support. Taking place over all four years, carefully integrated intensive short courses (normally one week duration) form the taught component of the EngD. These courses build on each other and augment the research. By using a core set of courses, graduates from a number of physical science/engineering disciplines can acquire the necessary background in materials. This is essential as there are insufficient numbers of students who have studied materials at undergraduate level. The research focus of this IDC will be the solution of academically challenging and industrially relevant processing-microstructure-property relationship problems, which are the corner-stones of the discipline. This will be possible because REs will interact with internationally leading academics and have access to a suite of state-of-the-art characterisation instrumentation, enabling them to obtain extensive hands on experience. As materials features as one of the University's seven research priority areas, there is strong institutional support as demonstrated in the Vice Chancellor's supporting letter, which pledges 2.07M of new money for this IDC. As quality and excellence run through all aspects of this IDC, those graduating with an EngD in MiNMaT will be the leaders and innovators of tomorrow with the confidence, knowledge and research expertise to tackle the most challenging problems to keep UK industry ahead of its competitors.

Evolution over the eons has made Nature a treasure trove of clever solutions to sustainability, resilience, and ways to efficiently utilize scarce resources. The Centre for Nature Inspired Engineering will draw lessons from nature to engineer innovative solutions to our grand challenges in energy, water, materials, health, and living space. Rather than imitating nature out of context or succumbing to superficial analogies, research at the Centre will take a decidedly scientific approach to uncover fundamental mechanisms underlying desirable traits, and apply these mechanisms to design and synthesise artificial systems that hereby borrow the traits of the natural model. The Centre will initially focus on three key mechanisms, as they are so prevalent in nature, amenable to practical implementation, and are expected to have transformational impact on urgent issues in sustainability and scalable manufacturing. These mechanisms are: (T1) "Hierarchical Transport Networks": the way nature bridges microscopic to macroscopic length scales in order to preserve the intricate microscopic or cellular function throughout (as in trees, lungs and the circulatory system); (T2) "Force Balancing": the balanced use of fundamental forces, e.g., electrostatic attraction/repulsion and geometrical confinement in microscopic spaces (as in protein channels in cell membranes, which trump artificial membranes in selective, high-permeation separation performance); and (T3) "Dynamic Self-Organisation": the creation of robust, adaptive and self-healing communities thanks to collective cooperation and emergence of complex structures out of much simpler individual components (as in bacterial communities and in biochemical cycles). Such nature-inspired, rather than narrowly biomimetic approach, allows us to marry advanced manufacturing capabilities and access to non-physiological conditions, with nature's versatile mechanisms that have been remarkably little employed in a rational, bespoke manner. High-performance computing and experimentation now allow us to unravel fundamental mechanisms, from the atomic to the macroscopic, in an unprecedented way, providing the required information to transcend empiricism, and guide practical realisations of nature-inspired designs. In first instance, three examples will be developed to validate each of the aforementioned natural mechanisms, and simultaneously apply them to problems of immediate relevance that tie in to the Grand Challenges in energy, water, materials and scalable manufacturing. These are: (1) robust, high-performance fuel cells with greatly reduced amount of precious catalyst, by using a lung-inspired architecture; (2) membranes for water desalination inspired by the mechanism of biological cell membranes; (3) high-performance functional materials, resp. architectural design (cities, buildings), informed by agent-based modelling on bacteria-inspired, resp. human communities, to identify roads to robust, adaptive complex systems. To meet these ambitious goals, the Centre assembles an interdisciplinary team of experts, from chemical and biochemical engineering, to computer science, architecture, materials, chemistry and genetics. The Centre researchers collaborate with, and seek advice from industrial partners from a wide range of industries, which accelerates practical implementation. The Centre has an open, outward looking mentality, inviting broader collaboration beyond the core at UCL. It will devote significant resources to explore the use of the validated nature-inspired mechanisms to other applications, and extend investigation to other natural mechanisms that may inform solutions to problems in sustainability and scalable manufacturing.
