Solid electrolyte structure and method for forming

摘要

Solid oxide electrolyte structures, e.g., flat plates, suitable for use in an electrochemical energy converter are prepared by a plasma deposition technique. This process is comprised of forming a suspension of the oxide powders, passing the suspension through an arc discharge to melt the oxide particles and depositing the molten particles on a substrate. The deposited layer is allowed to cool and then is removed intact from the substrate. The plate then can be sintered and a fuel electrode material and an oxidizer electrode material can be applied on the opposing surfaces of the plate.
