A fuel cell (100) is provided that includes a hydrogen separation membrane (10), an electrolyte membrane (20), provided on the hydrogen separation membrane, that has a proton conductivity and includes a perovskite type electrolyte having a A<SUB>1-X</SUB>A'<SUB>X</SUB>B<SUB>1-y-z</SUB>B'<SUB>y</SUB>B"<SUB>z</SUB>O<SUB>3</SUB> structure, and a cathode (30) provided on the electrolyte membrane. The tolerance factor T of the perovskite type electrolyte satisfies 0.940 = T = 0.996. |
