INORGANIC CONDUCTIVE MEMBRANE, FUEL CELL CONTAINING THE SAME, AND METHOD FOR MANUFACTURING THEREOF

摘要

PURPOSE: A manufacturing method of a fuel cell is provided to compose an ion conductive membrane by inorganic material, thereby obtaining a fuel cell which has no leakage of fuel even in case temperature changes. CONSTITUTION: A manufacturing method of a fuel cell comprises: a step of applying negative current by arranging wire at location separated from a metal plate by specific distance, and applying positive electrode current to the metal plate; a step of forming inorganic ion conductive membrane including pores one at least one side by adding electrolyte on the metal plate and the wire; a step of removing at least a part of the residual metal plate; a step of forming a catalyst layer by impregnating catalytic parent liquid on both sides of the inorganic membrane; and a step of mounting sulfonic groups on pores by contacting organic solution containing sulfonic groups to the catalyst layer.
