Title:
燃料電池用ガス拡散層及びその製造方法
Document Type and Number:
Japanese Patent JP5839161
Kind Code:
B2
Abstract:
A gas diffusion layer for a fuel cell includes a gas diffusion layer substrate and a microporous layer formed on the surface of the gas diffusion layer substrate. The microporous layer is formed into a sheet-like shape including a binder and a carbon material containing at least scale-like graphite, and the sheet-like microporous layer is attached to the gas diffusion layer substrate. The gas diffusion layer for a fuel cell having such a configuration, prevents the components included in the microporous layer from entering the gas diffusion layer substrate, so as to ensure gas permeability. In addition, the scale-like graphite contained in the microporous layer as an electrically conductive material improves electrical conductivity and gas permeability. Accordingly, the gas diffusion layer contributes to an improvement in performance of a polymer electrolyte fuel cell.
