POROUS CURRENT COLLECTOR, METHOD FOR MANUFACTURING SAME, AND FUEL CELL THAT USES POROUS CURRENT COLLECTOR

摘要

To provide a porous current collector that can be produced at a low cost, has high heat resistance and high oxidation resistance, has a required mechanical strength, and, in the case of being applied to a fuel cell operated at a high temperature, can exhibit high durability. A porous current collector 1,112a is used in a fuel cell 100 including a solid electrolyte layer 101, a first electrode layer 102 disposed on a side of the solid electrolyte layer 101, and a second electrode layer 105 disposed on another side of the solid electrolyte layer 101, the porous current collector 1,112a including continuous pores 1b and a Ni-Sn alloy layer 10a covering at least a surface of the porous current collector 1,112a.
