TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The device further comprises electrolyte. Preferred Process: The protonated compounds prior to use in the device are heated to 50-450 degrees C under an electric field of 1 E5V/M-400 E6V/M for l mu second-500000 seconds, to form a proton concentration gradient in the protonated perovskite core shell particles.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The protonated compound has proton concentration of 0.1-70% by equivalent concentration of potential site occupation of ABO3 perovskite-O-oxygen site occupation in perovskite oxide particle ceramic of the core-shell submicron or nanoparticles. The protonated compound is chosen from lead titanate, barium titanate, (strontium, barium)titanate, calcium titanate, strontium titanate, sodium bismuth titanate (Na0.5Bi0.5TiO3), lithium bismuth titanate (Li0.5Bi0.5TiO3), (sodium, cerium)titanate, barium zirconate, barium(zirconium, yttrium)oxide, barium cerium oxide, ytterbium doped strontium cerium oxide, neodymium doped barium cerium oxide, (silver, lithium)niobium oxide, potassium sodium niobium oxide ((K0.5Na0.5)NbO3), (silver lithium)tantalum oxide, (silver lithium)antimony oxide, sodium magnesium fluoride and ytterbium manganese oxide. Th content of protonated core shell perovskite particle material in the electrolyte film is 70 volume% or more of the electrolyte. The composition comprises protonated perovskite particles (10-9.9 volume%). The proton conducting electrolyte comprises a mixture of core shell protonated material (1-99 volume%), proton conducting ionomer (0.0-20 volume%) and oxide dielectric (0.0-40 volume%). Preferred Material: The shell material is chosen from proton barrier material and electrochemically active material. The core-shell material is subjected to reversible charge separation. The shell material is a proton barrier material which coats an outer surface of the core perovskite particle material. The shell includes a shell material (I) comprising proton barrier material in contact with the core material, or electrochemically active material in contact with the core material, and a shell material (II) comprising an electrochemically active shell material in contact with the proton barrier material or intermediate shell material (II) comprising a proton barrier shell layer in contact with the shell material (I), and an outer electrochemically active shell material in contact with the intermediate shell material. The shell material is a graded shell which varies from inner proton barrier to electrochemically active outer layer. Preferred Component: The electrochemically active shell material is chosen from aluminum hydroxide, calcium hydroxide and magnesium hydroxide. The proton barrier shell material is chosen from alumina, silica, calcium oxide, silicon nitride and aluminum nitride. The electronically insulating nanotubes are chosen from carbon nanotubes, aluminosilicate nanotubes, titania nanotubes, nitride nanotubes and oxide nanotubes. The electronically insulating nanoporous material is chosen from zeolites and nanoporous sol gel dielectrics. The anode comprises a conductive metal and a proton conductive metal hydride.
