Abstract
The present invention provides an electrode for fuel cell comprising a gas diffusion layer comprising porous polymer containing an electro-conductive filler and a catalyst layer containing a particulate catalyst. In this structure, a gas diffusion layer is formed by a porous polymer containing an electro-conductive filler. In this arrangement, the gas diffusion layer can be easily kept in face contact with the interface with the catalyst layer to increase the contact area of the gas diffusion layer with the catalyst layer. Thus, the number of catalyst particles taking part in the transfer of electron, making it possible to raise the output of the fuel cell.
