An electrolyte matrix is integrated with at least one electrode catalyst layer, namely, catalyst layers which can be independent from an electrode substrate. Therefore, the permeation of catalyst to the substrate can be prevented, the amount of catalyst used can be reduced, and an electrode of uniform thickness and composition can be produced and used.
