Isotopic exchange between hydrogen from the gas phase and proton-conducting oxides: Theory and experiment

摘要

The interaction of hydrogen isotopes from the gas phase with proton-conducting oxides with the perovskite structure La1-xSrxScO3-alpha (x = 0; 0.04) was studied by means of the hydrogen isotope exchange with gas phase equilibration in the temperature range T = 300-800 degrees C and in hydrogen pressure range pH(2) = 2-20 mbar.
