A reinforced electrolyte membrane for a fuel cell which is reinforced by a porous membrane, characterized by containing void portions in a joining portion between the surface of the porous membrane and/or pore surface and the electrolyte for buffering swelling when water is contained. This reinforced electrolyte membrane for a fuel cell has improved dimensional stability even if the electrolyte swells.
