In-Situ Analysis of the in-Plane Current Distribution Difference between Electrolyte-Supported and Anode-Supported Planar Solid Oxide Fuel Cells by Segmented Electrodes
Abstract:In the planar solid oxide fuel cell (SOFC), the fuel/oxidant distributions cause current and temperature distributions over the electrodes under the separator (interconnector) ribs and flow channels. Optimized designs of the separator to improve the output power and chemical/thermo-mechanical durability of practical stacks require numerical models validated by in-situ current distributions measured. We have therefore clarified the difference of in-situ measurements in-plane spatial current variations between a… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
