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
