title: Redox-Reversible Iron Orthovanadate Cathode for Solid Oxide Steam Electrolyzer.
abstract: A redox-reversible iron orthovanadate cathodeis demonstrated for a solid oxide electrolyser with up to 100% current efficiency for steam electrolysis. The iron catalyst is grown on spinel-type electronic conductor FeV2O4by in situ tailoring the reversible phase change of FeVO4to Fe+FeV2O4in a reducing atmosphere. Promising electrode performances have been obtained for a solid oxide steam electrolyser based on this composite cathode.
