ABSTRACT:
A compact, 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 alloys or silicon carbide or platinum alloys can be used to form the interconnector. The electrolyte and interconnector plates can be assembled into a converter stack at an elevated temperature such that upon cooling and during subsequent operational temperature excursions, the electrolyte plates will remain in compression. The stacks can be connected together to form modules which can be used as stand-alone electricity generators or used in combined cycle, cogeneration and gasifier systems.
