Abstract
A proton conductor is a proton conductor represented by a composition formula of BaZrYInO, and x and y in the composition formula satisfy 0<y≤0.013 and 0<x+y<0.5. A small amount of In is added to the composition in a predetermined range, whereby a resistance of the crystal grain boundary of the proton conductor can be decreased so as to compensate for or even exceed the increase in resistance in the crystal gains of the proton conductor caused by the addition of In, and as a result, the entire resistance can be decreased.
