Patent ID: 8728681

Claim:
A method of manufacturing a fuel cell, comprising: (a) disposing a conductive wire either within a metal tube or at a location spaced apart from a metal plate, the conductive wire and either the metal tube or the metal plate made of the same material, supplying an anode current to the conductive wire, and supplying a cathode current to the metal tube or the metal plate; (b) applying an electrolyte to the conductive wire and either the metal tube or the metal plate for forming an inorganic membrane comprising a plurality of pores in either at least a part of an inside wall and outside wall of the metal tube or at least one side of the metal plate to which the cathode current has been supplied and thereby forming an inorganic ion conductive membrane, wherein the electrolyte is a non-polymeric sulfuric acid solution; (c) removing at least a part of the metal tube or the metal plate remaining intact after forming the inorganic membrane, by using an etching method; and (d) dipping an inside wall and outside wall of the inorganic membrane or both sides of the inorganic membrane in a noble metal series catalyst mother liquid to form a catalyst layer.
