Abstract:
1. A gas diffusion electrode for a fuel cell, comprising; a hydrophilic porous layer including an electrically conductive material and an ion conductive material; and a catalyst layer adjacent to the hydrophilic porous layer, wherein a water transport resistance of the hydrophilic porous layer is smaller than a water transport resistance of the catalyst layer; wherein the hydrophilic porous layer comprises a first electrically conductive material, a first ion conductive material covering a part of a surface of the first electrically conductive material, a second electrically conductive material, and a second ion conductive material covering a part of a surface of the second electrically conductive material; and wherein the first electrically conductive material has a cover area of 200 to 1600 m
