PROBLEM TO BE SOLVED: To provide an air pole current collector of a solid electrolyte fuel cell. SOLUTION: The current collector is made of a porous Ni group alloy which contains in mass % Cr: 13-45% and as necessary Fe: 1-38%, and as necessary one or two or more kinds out of W: 0.1-20%, Mo: 0.1-10%, Nb: 0.1-4%, Ta: 0.1-4%, Co: 0.1-10%, and as necessary one or two or more kinds out of Al: 0.1-10%, Si: 0.01-3%, and Ti: 0.01-3%, and further as necessary one or two or more kinds out of La: 0.001-0.05%, Y: 0.001-0.05%, Zr: 0.001-0.2%, and the content of C and Mn is defined respectively as C: 0.15% or less and Mn: 2% or less and the rest is composed of Ni and unavoidable impurity, and which has a total porosity of 70-97%. |
