CATALYST LAYER TRANSFER FILM

摘要

PROBLEM TO BE SOLVED: To provide a catalyst layer transfer film which prevents a defect portion (a void of the catalyst layer) from occurring in a catalyst layer and has good transfer properties.

SOLUTION: The catalyst layer transfer film for transferring a catalyst layer of a polymer electrolyte fuel cell comprises a substrate, and a catalyst layer layered on a release layer formed on one side of the substrate, wherein the release layer contains silicon oxides.
