Investigation of Electroactive Polymers for the PEMFC GDL Available to Purchase

In this work, electroactive polymers (EAPs) are introduced as novel materials for the polymer electrolyte membrane fuel cell (PEMFC). Polypyrrole (PPy) is selected as a promising EAP for the PEMFC. The fabrication procedures including the polymer solution preparation and the electro-chemical deposition process for producing a thin and porous PPy film are presented. The activation behavior of PPy thin film is observed, and the surface properties are analyzed.
