Abstract

Abstract : Reactive spray deposition technology (RSDT) is a cost-effective method for producing high performance proton exchange membrane fuel cell (PEMFC) membrane electrode assemblies (MEAs). In this study, we used the RSDT process to deposit catalyst-coated membrane (CCM) with Pt supported on Ketjen Black (KB), multi-wall carbon nanotube (MWCNT), and reduced-graphene oxide (rGO) with ultra-low Pt loading in order to elucidate the influence of the support and Pt dispersion on the catalyst perfromance. The electrochemically active surface area (ECSA), activity for oxygen reduction reaction (ORR) and PEMFC performance are investigated and compared.
