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.

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

High Performance Anode for Direct Ammonia Solid Oxide Fuel Cells. Solid oxygen fuel cells are a clean energy generation device with very high energy efficiency and if with hydrogen as fuel, the emission is zero. However, the utilisation of hydrogen is limited by on-board storage. Ammonia is a promising hydrogen carrier and can be directly fed to solid oxide fuel cells without fuel storage problem, and the products are just hydrogen and nitrogen.
