Development of novel cathodes for next generation solid oxide fuel cells. This project will provide novel cathodes to reduce the operating temperature of the Solid Oxide Fuel Cell (SOFC) as low as 500 degrees celsius. The technology may lead to widespread utilization of SOFCs, thus providing great assistance to Australia's industries in term of reducing carbon dioxide emission and easing pressure from carbon tax.
Hybrid cathode for low temperature solid oxide fuel cells. This project aims to develop molten carbonate-perovskite hybrid cathode materials for low temperature solid oxide fuel cells (LT-SOFCs) possessing both high catalytic activity towards oxygen reduction reaction (ORR) and high tolerance to carbon dioxide poisoning. Carbon dioxide in air can poison nearly all the perovskite cathode materials developed for LT-SOFCs (below 600 degrees C) so far. These materials will not be practically useful ....Hybrid cathode for low temperature solid oxide fuel cells. This project aims to develop molten carbonate-perovskite hybrid cathode materials for low temperature solid oxide fuel cells (LT-SOFCs) possessing both high catalytic activity towards oxygen reduction reaction (ORR) and high tolerance to carbon dioxide poisoning. Carbon dioxide in air can poison nearly all the perovskite cathode materials developed for LT-SOFCs (below 600 degrees C) so far. These materials will not be practically useful until carbon dioxide poisoning can be prevented. This project expects to make these LT-SOFC cathode materials commercially viable, solving a problem for the widespread use of low temperature solid oxide fuel cells.Read moreRead less

This project aims to create new avenues for well-controlled large-scale synthesis of hierarchical nanoporous platinum-based architectures, and develop applications for the resultant new electrocatalysts. Developing novel high-performance, low-cost, and long-life electrode catalysts can improve the efficiency, cost, and durability of energy conversion technology. The project plans to use the unique properties of well-defined nanoarchitectures to reduce platinum content and to improve electrocatalytic performance. Nanoporous systems in electrocatalysts can provide more active sites and effective surface permeability, which should enhance catalytic activity. Project outcomes may also contribute to our understanding of the relationships among morphologies, pore structures, surface atomic structures and catalytic activities to guide the development of other kinds of high performance nanoporous catalysts.Read moreRead less
A defect mechanism for oxygen reduction reaction. This project aims to use defective carbon to replace expensive platinum as a catalyst for oxygen reduction reaction (ORR) in fuel cells. Defective carbons incorporating non-precious metals are better than platinum in terms of over-potential, current density and number of electron transfer. They reduce the overall fuel cell cost but their better stability and higher open voltage and power density promise huge commercial benefit. This project is ex ....A defect mechanism for oxygen reduction reaction.

Oxide-based high temperature proton exchange membrane fuel cells. Proton exchange membrane fuel cells (PEMFCs) are one of the most efficient energy conversion technologies for producing electricity from fuels such as hydrogen and methanol. Current PEMFCs use precious metal catalysts, and the performance of liquid methanol fuel is disappointingly low due to the inability of polymer or hybrid membranes to operate at temperatures above 160-180 degrees centigrade. This work aims to develop an all ox ....Oxide-based high temperature proton exchange membrane fuel cells. Proton exchange membrane fuel cells (PEMFCs) are one of the most efficient energy conversion technologies for producing electricity from fuels such as hydrogen and methanol. Current PEMFCs use precious metal catalysts, and the performance of liquid methanol fuel is disappointingly low due to the inability of polymer or hybrid membranes to operate at temperatures above 160-180 degrees centigrade. This work aims to develop an all oxide-based PEMFC technology using a recently developed sintered and heteropolyacid functionalised mesoporous silica membrane. The utilisation of all-oxide-PEMFCs using non-precious metal catalysts is expected to significantly enhance the power density, reduce costs, and enhance the commercial viability of PEMFC technologies.Read moreRead less
