TI - Optimization of PtIr electrocatalyst for PEMURFC KW - PEMFC KW - REGENERATIVE FUEL CELL KW - BIFUNCTIONAL ELECTROCATALYST KW - PTIR N2 - For the fabrication of high-efficient bifunctional electrocatalyst of oxygen electrode, several electrocatalysts were prepared and tested on the URFC performance including both fuel cell and water electrolysis in a single cell URFC system. The catalysts revealed fuel cell performance in the order of Pt black>PtIr>PtRuOx>PtRu ¡« PtRuIr>PtIrOx and water electrolysis performance in the order of PtIr ¡« PtIrOx>PtRu>PtRuIr>PtRuOx ¡« Pt black. Considering both results PtIr showed the best URFC performance. With increasing Ir or IrOx composition from 0 to 50 wt UR - https://drive.google.com/file/d/1mx6bIEDp5DbgaUAlGAaZ3k0rUIBAyGiH/view?usp=drivesdk ER -
