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
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.
