PROBLEM TO BE SOLVED: To provide a fuel cell anode capable of improving strength while maintaining ion conductivity, and a fuel cell single cell including the fuel cell anode.SOLUTION: A fuel cell anode 10 includes an anode 1, a solid electrolyte layer 2, and a cathode 3, and is used for a fuel cell single cell 5 using the anode 1 as a support. The fuel cell anode 10 includes an anode base layer 12 having both of a function as the anode 1 and a function as the support. The anode base layer 12 comprises a mixture including a catalyst 121, and a core-shell structure 122 having a core part 122a and a shell part 122b covering the outer periphery of the core part 122a. The core part 122a comprises an inner solid electrolyte having a crystal phase mainly composed of tetragonal crystals, and the shell part 122b comprises an outer solid electrolyte having a crystal phase mainly composed of cubic crystals. |
