Abstract
The mixed ion-electron conducting Cu-cermet membranes are suggested for hydrogen production by water splitting at moderate temperature (873-1173oC) because of their good de-catalyzing carbon-formation reactions. The logarithmic hydrogen production rates with pH2O in the oxidizing gas and with pH2 in the reducing gas were investigated. Cu-based cermet membranes should be further studied to enhance their relatively poor thermal stability, with severe agglomerates of the Cu phase observed following operation at 1173K.

Keywords: water splitting, cermet membranes.
