The structural and electrochemical characteristics of the bimetallic catalysts were examined by the TGA, XRD, XPS, and CV techniques. ECHP Tests were performed with reformate gas mixtures containing hydrogen (H2), carbon monoxide (CO), and carbon dioxide (CO2) at temperatures between 140-180°C. The gas at the exit of the ECHP cell was analyzed with the gas chromatography device (GC), and high H2 purity was achieved. © 2022 Proceedings of WHEC 2022 - 23rd World Hydrogen Energy Conference: Bridging Continents by H2.
