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.
