Abstract
A porous electrode-supported electrolyte membrane according to the present embodiment includes an electrolyte membrane and a porous reduction electrode directly bonded onto the electrolyte membrane, in which the porous reduction electrode has an average pore diameter of 1 μm or more. In a step of bonding the electrolyte membrane and the porous reduction electrode, pressure is applied while heat is applied so that the electrolyte membrane is prevented from swelling.
