GAS DIFFUSION ELECTRODE BASE MATERIAL PRECURSOR, GAS DIFFUSION ELECTRODE BASE MATERIAL, GAS DIFFUSION ELECTRODE, AND FUEL CELL

摘要

PPROBLEM TO BE SOLVED: To provide a precursor having flexibility suitable for continuous machining as a gas diffusion electrode base material, and capable of forming the gas diffusion electrode base material high in bending strength and compressive strength; and to provide a gas diffusion electrode base material, a gas diffusion electrode and a fuel cell using it. PSOLUTION: This gas diffusion electrode base material contains a compound fiber provided with an adhesive carbonizable resin thermally adhesive and carbonizable by baking at least at a part of a surface of a fiber having conductivity after baking and capable of being made conductive, and is formed of a fiber sheet with the adhesive carbonizable resin stuck. This gas diffusion electrode base material, this gas diffusion electrode and this fuel cell are formed by using the gas diffusion electrode base material. PCOPYRIGHT: (C)2004,JPO&NCIPI
