Abstract (en)
[origin: WO02056404A1] A catalyst composition for a cell comprising catalyst-bearing conductive powder particles and fibrous carbon. A membrane-electrode assembly for a fuel cell comprising an electrolyte membrane and an electrode including a catalyst layer and a gas diffusion layer, the electrode being provided on each surface of the electrolyte membrane, wherein at least a portion of the surface of the gas diffusion layer which is in contact with the catalyst layer includes a layer containing a hydrophobic resin and fibrous carbon.
