| Research Abstract |
A new method of protonating oxides, via change in oxidation state of transition metal dopant was examined to create a brand new proton conducting oxides that possibly operate at intermediate-low temperatures. Experimental results suggested protonation taking place in Mn-doped SrZrO_3 and Mn-doped LaYbO_3. It is elucidated that the present method of protonation can work for oxides. On the other hand, LaYbO_3 has been found as a high protonic conductor even of transition metal was not introduced to be further investigated.
