Abstract: PURPOSE: A manufacturing method of porous composite material is provided to sinter in moisture at temperature which is 200-300°C lower than the existing sintering method, thereby restraining the grain growth of the composite. CONSTITUTION: A manufacturing method of porous composite material comprises: a step of mixing ion conductive oxide, transition metal oxide and pore-forming agent; a step of pressure-molding and sintering by adding heat generated by current to the mixture; and a step of cooling the mixture. The sintering step conducted at 1000-1200°C within 5 minutes. The pressure-molding is conducted with the range of 10-80MPa. The heat generated by current is heat through induced current.
