Tohoku University Technology: Method for producing Proton-containing oxides : T21-224
Expand the variety of proton-containing ceramics.
In order to commercialize various ceramic electrochemical devices such as fuel cells, hydrogen production cells, hydrogen sensors, ammonia synthesis cells, etc., research and development of proton-conducting oxides has been actively carried out. However, high proton conductivity has been achieved only for oxides in a few type of crystal structures. This makes difficult to develop practical proton-conducting ceramics having mixed conductivity, chemical stability, and sinterability. The present invention is an ion-exchange technique using a high-temperature acidic liquid. This technique enables easy conversion from a wide variety of aprotic oxides to oxides containing proton at a high level.
