Production of Ni-Based Glassy Alloy-Coated Bipolar Plate with Hydrophilic Surface for PEMFC and Its Evaluation by Electrochemical Impedance Spectroscopy
Abstract:In this study, Ni 65 Cr 15 P 16 B 4 glassy alloy-coated bipolar plates with a hydrophilic surface were produced and the power generation properties of a single fuel cell with such plates were investigated, SUS316L and graphite bipolar plates also being produced for comparison. The fuel cell with the glassy alloy-coated bipolar plates showed good IV performance after repeated IV scans for membrane activation as did the cell with the graphite bipolar plates. After 30 IV scans for activation, a long-time power ge… 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.
