Non‐destructive platinum catalyst‐replenishment method for deteriorated polymer electrolyte membrane fuel cells
2021
Energy Science & Engineering
A novel method for replenishing platinum catalysts on an electrolyte membrane of polymer electrolyte membrane fuel cell (PEMFC) is studied. The method injects electrocatalyst-supplementing ink into a pre-assembled fuel cell in a simple and non-destructive manner. For replenishing, straightforward catalystreplenishment equipment and corresponding protocol are proposed. The protocol consists of injection, penetration, and purge processes. As a feasibility study, the method is performed on fuel
