Investigation of La1-xSrxCrO3-∂ (x ~ 0.1) as Membrane for Hydrogen Production.

Various inorganic membranes have demonstrated good capability to separate hydrogen from other gases at elevated temperatures. Hydrogen-permeable, dense, mixed proton-electron conducting ceramic oxides offer superior selectivity and thermal stability, but chemically robust candidates with higher ambipolar protonic and electronic conductivity are needed. In this work, we present for the first time the results of various investigations of La1-xSrxCrO3-∂ membranes for hydrogen production.
