Abstract

An abnormal increase (by up to 15 times as compared to the equilibrium value) in the conductivity of high-temperature protonic solid electrolyte BaZr0.95Nd0.05O3−δ upon a rapid change of an oxidative atmosphere to a hydrogen-containing reductive one is discovered. The reverse change of the atmospheres results in an abnormal decrease in the protonic conductivity. The effect is explained by an interaction of hydrogen with nonequilibrium electronic holes in the electrolyte.
