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. The A element is an alkaline-earth metal and is contained in a range of 0.4<a<0.9, where the a value represents a mole fraction of this element, and the B′ element is a trivalent group 3 or group 13 element and is contained in a range of 0.2<x<0.6, where the x value represents a mole fraction of this element.
Claims8
A proton conductor having a perovskite-type crystal structure expressed by the compositional formula AaB1-xB′xO3-δ, wherein:
- the proton conductor is composed of a single phase which is substantially uniform in composition and crystal structure,
- A is at least one selected from among alkaline-earth metals,
- B is a tetravalent group 4 transition metal or Ce, and
- B′ is a trivalent group 3 or group 13 element,
- where 0.4<a<0.9 and 0.2<x<0.6 are satisfied.
