Abstract
In a method of producing a membrane electrode assembly, a solid polymer electrolyte membrane and gas diffusion layers are stacked together in a stacking direction in a manner that electrode catalyst layers are interposed between at least parts of the solid polymer electrolyte membrane and the gas diffusion layers to form a stack body. A load is applied to the stack body in the stacking direction, and the temperature of the solid polymer electrolyte membrane is increased by high frequency dielectric heating. In this manner, the gas diffusion layers, the electrode catalyst layers, and the solid polymer electrolyte membrane are joined integrally to obtain the membrane electrode assembly.
