ABSTRACT:
A compact, light-weight solid-oxide electrochemical converter can be achieved using thin plates of electrolyte and interconnector. Impermeable, straight, thin plates of solid-oxide electrolyte are fabricated by high energy plasma spray methods under controlled temperature conditions. Thin sheets of nickel or platinum alloys can be used to form the interconnector. A protective coating is preferred on the contact points to provide electrical continuity when nickel alloys are employed. Stamping or electrodeposition techniques can be used to form corrugated patterns for reactant distribution over the surfaces of each electrolyte plate.
