Patent ID: 7910262

Claim:
A solid type electrolyte fuel cell comprising: an electric power generation cell made up of a solid electrolyte layer, a fuel electrode layer and an air electrode layer; a fuel electrode current collector disposed to be in close contact with the fuel electrode layer; and an air electrode current collector disposed to be in close contact with the air electrode layer, wherein the air electrode current collector comprises a silver porous body, wherein the silver porous body is a sponge metal porous body having a skeletal structure, wherein a porosity of the silver porous body is within a range from 60% to 97%, wherein the porous body is reinforced by a mesh metal body, wherein the mesh metal body is made of silver or silver alloy, or a metal matrix which is other than silver or silver alloy and is coated with silver or silver alloy, and wherein the mesh metal body is the metal matrix other than the silver or the silver alloy, the metal matrix is plated with nickel, and is plated with silver while the nickel plating is used as an under layer.
