摘要:
An object of the present invention is to provide an electrolyte membrane that suppresses swelling and shrinkage caused by water retained in the electrolyte membrane for a solid polymer-type fuel cell, improves the durability of the electrolyte membrane, and obtains excellent power generation characteristics with a low resistance. The electrolyte membrane for a solid polymer-type fuel cell includes, as a reinforcing membrane, a nonwoven fabric composed of an electrolyte material and PVDF bicomponent fibers 2a, thereby improving the durability of the electrolyte membrane. Furthermore, the bicomponent fiber 2a has pores 23 that can effectively retain generated water, thereby improving battery performance under the condition of a low humidity.

摘要:
This solid polymer fuel cell has a plurality of stacked single battery modules having an electrolyte membrane, electrode layers disposed on both surfaces of the electrolyte membrane, and a pair of separators provided with a gas flow paths disposed on the inside surfaces so as to sandwich the electrode layers. The electrolyte membrane is provided with electrolyte material and a nonwoven fabric which is embedded in the electrolyte material. The nonwoven fabric is provided with a plurality of fused parts that are provided in a linear shape or spotted shape on a part of the nonwoven fabric that is a part corresponding to of the solid polymer fuel cell, wherein two or more nonwoven fibers are fused to each other and the thickness thereof is thinner than the membrane thickness of the unwoven fabric.
摘要:
An electrolyte membrane for solid polymer fuel cell includes a reinforce membrane made of nonwoven fibers and an electrolyte provided in a space among the nonwoven fibers. The nonwoven fibers have a non-uniform mass distribution in a plane of the electrolyte membrane. A mass of the nonwoven fibers per unit area in a region corresponding to at least part of a peripheral portion of a fuel cell-use gasket frame is greater than a mass of the nonwoven fibers per unit area in a region corresponding to a center portion of the gasket frame. The electrolyte membrane for solid polymer fuel cell is attached to the fuel cell-use gasket frame.
