Title:
MEMBER FOR FUEL CELL GAS DIFFUSION LAYER, ITS MANUFACTURING METHOD, AND FUEL CELL
Document Type and Number:
Japanese Patent JP2008066293
Kind Code:
A
Abstract:
To provide a member for a polymer fuel cell gas diffusion layer and its manufacturing method, excellent in drainage property, gas diffusion property and conductivity, with a high adhesion property with a catalyst layer, and further, excellent in power generation efficiency by preventing damages of a catalyst layer electrolyte membrane joint body.
A plurality of porous conductive base materials 181 are laminated, and conductive particles 182 are pinched between the base materials. In the manufacturing method, after the conductive particles are uniformly dispersed on at least one side of a surface of the porous conductive base material, further, the porous conductive base material is laminated on a surface having the conductive particles.
