A fuel cell (100) is provided that includes a hydrogen separation membran e (10), an electrolyte membrane (20), provided on the hydrogen separation me mbrane, that has a proton conductivity and includes a perovskite type electr olyte having a A1-XA'XB1-y-zB'yB"zO3 structure, and a cathode (30) provided on the electrolyte membrane. The tolerance factor T of the perovskite type e lectrolyte satisfies 0.940 <= T <= 0.996. |
