摘要： PROBLEM TO BE SOLVED: To provide a gas diffusion layer which simultaneously achieves high gas permeability and high conductivity, even when compressive pressure is applied to the gas diffusion layer in order to obtain a stack structure.SOLUTION: A membrane-electrode assembly comprises a porous aggregate structure 30 composed of thermally fusible organic fibers OF which can be thermally fused to each other by heating. In the porous aggregate structure 30, carbon fibers CF are bound each other by a binder resin along with conductive particulates, so that the porous aggregate structure 30 having relatively high rigidity is formed in gas diffusion layers 18 and 20 by mutual binding of relatively low amounts of thermally fusible organic fibers OF. Furthermore, since the thermally fusible organic fibers OF has a fiber length within the range of 0.2 to 3 of a ratio of the film thickness of the gas diffusion layer to the fiber length, (the film thickness of the gas diffusion layer)/(the fiber length) it is possible to obtain the gas diffusion layers 18 and 20 which simultaneously achieve high gas permeability and high conductivity, even when compressive pressure is applied.

摘要： PROBLEM TO BE SOLVED: To provide a base material for a gas diffusion electrode, which exhibits high conductivity, gas permeability, and high water-repellency without using fluorine and to provide a method of manufacturing the material and an MEA containing the material. SOLUTION: Each base material 18, 20 for a gas diffusion electrode contains carbon fibers 26, carbon fine particles 28, and acrylic silicon resin 30. The respective carbon fibers 26 are joined by the acrylic silicon resin 30 with the carbon fine particles 28 interposed therebetween. Therefore, the base materials 18, 20 for the gas diffusion electrode have an advantage of the high water-repellency without containing fluorine using a water-repellency of the acrylic silicon resin 30 itself. In addition, since the base materials 18, 20 for the gas diffusion electrode are porus and are formed of many carbon fibers 26 and carbon fine particles 28, they exhibits high gas permeability. Also, the carbon fine particles 28 is contained in the material, which enhances the conductivity between the carbon fibers 26 and results in the materials to have high conductivity.

摘要： PROBLEM TO BE SOLVED: To provide a layer built fuel cell wherein permeation of an electrolyte solution into an electrode layer is sufficiently suppressed while forming a solid polymer electrolyte layer by applying it on the electrode layer, and output can be heightened as a result, and to provide its manufacturing method. SOLUTION: The air permeation flow rate of an electrode with a catalyst is adjusted within a range of 10,000-12,000 ml*mm/cm 2 /min. Therefore, when providing an electrolyte membrane 12 by applying an electrolyte solution on it, since permeation of the electrolyte solution into the catalyst layer 28 is suitably suppressed, it is suitably suppressed that gas diffusion performance of the catalyst layer 28 and the electrode 30 is deteriorated by the penetrated electrolyte or their reactivity with the catalyst is deteriorated. Thereby, this layer built fuel cell having high output can be obtained. COPYRIGHT: (C)2008,JPO&INPIT
