Abstract

La présente invention concerne un conducteur de protons qui a une structure pérovskite, et qui contient un oxyde métallique représenté par la formule (1) AxB1-yMyO3-δ (l'élément A représentant au moins un élément qui est sélectionné dans le groupe constitué par Ba, Ca et Sr ; l'élément B représentant au moins un élément qui est sélectionné dans le groupe constitué de Ce et Zr ; l'élément M représentant au moins un élément qui est sélectionné dans le groupe constitué de Y, Yb, Er, Ho, Tm, Gd, In et Sc ; x et y satisfont à 0,95 ≤ x ≤ 1 et 0 < y ≤ 0,5 ; et δ représentant la quantité de déficience en oxygène) et le cuivre élémentaire contenu dans l'oxyde métallique. Par rapport à ce conducteur de protons, le rapport du cuivre élémentaire RCu sur la quantité totale de l'élément A, de l'élément B et de l'élément M est de 0,01 % atomique à 0,6 % atomique (inclus).
