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.

摘要:
Disclosed is a foam-molded member having a skin with which peeling or floating does not occur when the skin is wrapped. Also disclosed is a method of manufacturing the foam-molded member having a skin. A foam-molded member having a skin, such as a door trim, includes a core, a skin, foam and a fixing member. The core can be folded at a folding portion, and the skin faces the core. The foam is filled in a space between the core and the skin. The fixing member fixes the core that is integrally formed with the skin and the foam and is folded at the folding portion. The core is divided into a body portion and an extension portion, with the folding portion serving as a boundary. The extension portion folded at the folding portion is fixed to the body portion by the fixing member.
