FIELD: electrical engineering.
SUBSTANCE: this membrane relates to electrochemical membranes for extraction of oxygen from gas mixes using in solid-oxide fuel elements, oxygen separators, ceramic membrane reactors, etc. Membrane material comprises composite containing the following elements, in wt %: V2O5 - 1-15%; BiVO4 makes the rest. Transfer of oxygen ions occurs, in said membrane, along fluid channels formed along grain boundaries at heating to over 650°C.
EFFECT: higher oxygen permeability compared with that of nitrogen, longer life in transfer of oxygen.
