Abstract
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.
