Patent ID: 10374243

Abstract:
Provided is a porous current collector which is used for a fuel electrode and has a high gas reforming function and high durability. A porous current collector 9 is provided adjacent to a fuel electrode 4 of a fuel cell 101 that includes a solid electrolyte layer 2, the fuel electrode 4 disposed on one side of the solid electrolyte layer, and an air electrode 3 disposed on the other side. The porous current collector includes a porous metal body 1 and a first catalyst 20. The porous metal body has an alloy layer 12a at least on a surface thereof, the alloy layer containing nickel (Ni) and tin (Sn). The first catalyst, which is in the form of particles, is supported on a surface of the alloy layer, the surface facing pores of the porous metal body, and is capable of processing a carbon component contained in a fuel gas that flows inside the pores.
