Science and technology” of protons in motion in solids is called protonics. This paper surveys the possible protonic devices using a proton conducting ceramic. They will contribute not only to the enhancement of the quality of technology at present but also to the construction of a hydrogen energy system in the near future. The protonic devices are classified into two categories; the devices utilizing electromotive force and those utilizing preferential transport of protons. Galvanic cell type hydrogen sensors and fuel cells belong to the former, and hydrogen pump, steam electrolyzer and membrane reactors to the latter. Many kinds of modifications can be derived, in principle, from the devices described above. Using high temperature proton conducting ceramics based on perovskite type oxides, some of the devices were made on a laboratory scale, and have been positively verified to work.
