Abstract:We established and developed an in situ X-ray absorption fine structure (XAFS) experimental testing device for characterizing hydrogen-oxygen proton exchange membrane fuel cells (PEMFC) on XAFS beamline BL14W1 at the Shanghai Synchrotron Radiation Facility (SSRF). XAFS data were collected under the operating state of the fuel cell with Pt/C and Pd/C as the cathode and anode catalysts, respectively, while the cell current-voltage (J-V) Curve and power density curves were monitored. Changes in the oxidation stat… 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.
