Title:
固体高分子型燃料電池用ガス拡散電極基材、その製造方法及びそれを用いた固体高分子型燃料電池
Document Type and Number:
Japanese Patent JP4388314
Kind Code:
B2
Abstract:
To provide a gas diffusion electrode for a solid polymer fuel cell in which adhesion of carbon black to a porous fiber sheet is excellent and there happens no clogging by supplied water and generated water, and adhesiveness with a catalyst layer is uniform and which is excellent in durability, its manufacturing method, and a solid polymer fuel cell using the same.
The gas diffusion electrode for the solid polymer fuel cell is made by forming a conductive porous layer containing a polyvinylidene fluoride compound and carbon black on at least one side of a porous fiber sheet, or is made by containing the polyvinylidene fluoride compound and carbon black inside a porous fiber sheet.
