Abstract: A method for preparing a porous metal oxide foam for an air electrode current collector interposed between an air electrode and a connector of a solid oxide fuel cell stack is provided to improve conductivity, chemical stability, gas penetration, mechanical strength and buffering property. A method for preparing a porous metal oxide foam for an air electrode current collector comprises the steps of coating a conductive metal oxide slurry on a porous polymer having a 3D network structure to prepare a polymer/metal oxide composite; heating the polymer/metal oxide composite to burn the polymer, thereby forming a porous metal oxide foam; and sintering the metal oxide foam. Preferably the porous polymer is any one selected from polyurethane, polystyrene and cellulose.
