SOLID ELECTROLYTE FUEL CELL

摘要

PURPOSE:To extend the life of a battery by preventing the generation of a low-conductivity material caused by the reaction between a solid electrolyte film and an oxygen electrode film. CONSTITUTION:An oxygen ion conducting thin film 2 made of a material chemically stable for both films is arranged between a solid electrolyte film 1 made of a solid solution of zirconium oxide and a bivalent or trivalent metal oxide and an oxygen electrode film 3 made of a lanthanum perovskite oxide.
