Abstract
An exemplary proton conductor according to the present disclosure has a perovskite-type crystal structure expressed by the compositional formula AaB1-xB′xO3-δ, where A is at least one selected from among group 2 elements; B is a group 4 element or Ce; B′ is a group 3 element, a group 13 element, or a lanthanoid element; 0.5<a≦1.0, 0.0≦x≦0.5, and 0.0≦δ<3; and the charge of the above compositional formula is deviated from electrical neutrality in a range of −0.13 or more but less than +0.14.
