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 will be achieved using modified silic ....Light Activated Electrochemistry: Microelectrode Arrays with just one wire. Electrochemistry requires each electrode to be connected to the external circuit by a wire. With many electrodes this means many wires. Wires limit electrode density in arrays and dictate that the electrode architecture must be predetermined. This project aims to remove the need for a wire for each electrode by using light to sequentially connect each electrode to a single wire. This will be achieved using modified silicon electrodes where irradiating with light causes an increase in conductivity at the illumination spot. The project will explore the variables that influence the spatial resolution and apply the ideas to making soft connects for nanoelectronics and making high density electrode arrays for electroanalysis.Read moreRead less
