Abstract

PURPOSE:To improve electric conductivity and a cell performance by using a graphite inter-layer compound impregnated with an acid as a substrate of its catalyst layer for a gas diffusion electrode of a fuel cell. CONSTITUTION:Negative and positive gas diffusion electrodes N, P are composed of a catalyst layer 1 using a graphite inter-layer compound as a substrate, and a diffusion layer 2 made of waterproofing carbon paper. Gas separators S made of carbon and incorporating gas feed paths 3, 4 for hydrogen and oxygen respectively and a matrix E holding a phosphoric acid electrolyte are laid between the negative and positive gas diffusion electrodes N, P to make up a matrix type fuel cell. A graphite inter-layer compound, used as the substrate of the catalyst layer 1 for the gas diffusion electrodes N, P, is impregnated with an acid, e.g., phosphoric acid or sulfuric acid between layers of the graphite. It is proper to bind this inter-layer compound by mixing with catalyst particles.
