METAL-SUPPORTED SOLID OXIDE CELL

A novel solid oxide cell consists of at least one layer containing steel (metal alloys consisting predominantly of Fe) [layer A "support"], in which the backbone of one or more layers [layer B ("anode" or "cathode")], that is located between layer A and a substantially dense ion-conducting layer [layer C "electrolyte"], is a cermet comprising a ceramic material with a metal alloy, in which the main metal component is neither nickel nor steel. The cell may comprise a further layer (layer D), which is a cathode layer, when layer B is an anode layer, and vice versa. This complete cell can be a solid oxide fuel cell (SOFC) as well as a solid oxide electrolysis cell (SOEC) depending on which of the electrodes serves as the anode.
