ELECTRODE FOR POLYMER ELECTROLYTE FUEL CELL, MEMBRANE/ELECTRODE ASSEMBLY AND PROCESS FOR PRODUCING CATALYST LAYER |
摘要 |
To provide an electrode for a polymer electrolyte membrane having high gas diffusion performance, a membrane/electrode assembly, and a process for producing a nonwoven structure for a catalyst layer, which can produce the membrane/electrode assembly inexpensively and easily. The catalyst layer 11 of the electrode comprises a nonwoven structure of an ion-exchangeable fluoropolymer fiber, wherein the fiber diameter of the fiber is from 0.1 to 30 mum, and the bulk density of the nonwoven structure is from 0.1 to 1.1 g/cc. The nonwoven structure is produced by forming fiber from a fiber spinning stock solution containing the ion-exchangeable fluoropolymer by an electrical field fiber spinning method, followed by gathering the fiber. A catalyst is blended in the fiber spinning stock solution or is adhered on the nonwoven structure.
