Protonics deals with the science and technology of protons in motion. A proton conducting ceramic is one of the promising advanced materials for energy saving and environmental conservation in the future. In this paper, the possibilities of protonics as a technology are surveyed and high temperature proton conducting oxide ceramics for them are reviewed with respect to materials, their electrochemical properties and their applications citing mainly the experimental results in the author’s laboratory.
