PROTON CONDUCTING OXIDIC ELECTROLYTE FOR INTERMEDIATE TEMPERATURE FUEL CELL

摘要

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 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 electrolyte satisfies 0.940 ≤ T ≤ 0.996.
