GAS DIFFUSION ELECTRODE MATERIAL AND PRODUCTING METHOD THEREOF |
摘要 |
A gas diffusion electrode material of the present invention includes: a porous body (1) formed of continuous and discontinuous polytetrafluoroethylene microfibers (2) and having three-dimensionally continuous micropores (4); and a conductive material (3) supported on the porous body (1). Moreover, a density of the polytetrafluoroethylene microfiber (2) is lower in a surface region (1A) of a cross section of the porous body (1) than in an intermediate region (1B) of the cross section. In accordance with the present invention, the polytetrafluoroethylene having the predetermined three-dimensional structure is used, and so on. Therefore, it is possible to provide a gas diffusion electrode material excellent in power generation characteristics and durability. |
