Abstract
A membrane electrode assembly includes an anode, a cathode, and a solid polymer electrolyte membrane interposed between the anode and the cathode. The anode and the cathode include gas diffusion layers and electrode catalyst layers. Mixture layers are provided over predetermined areas H around surfaces of the electrode catalyst layers. The electrode catalyst layers and adhesive layers are mixed in the mixture layers, respectively.
