SOLID OXIDE FUEL CELL, FUEL CELL MODULE, AND FUEL CELL DEVICE

摘要

A solid oxide fuel cell includes a solid electrolyte layer, a fuel electrode layer that is disposed on one surface of the solid electrolyte layer, an oxygen electrode layer that is disposed on the other surface of the solid electrolyte layer, and an intermediate layer that is disposed between the solid electrolyte layer and the oxygen electrode layer and that includes ceria-based particles containing rare earth elements other than cerium and ceramic particles consisting of oxide of a metallic element different from that of the ceria-based particles. The ceramic particles having a smaller average particle diameter than that of the ceria-based particles exist in grain boundaries of the ceria-based particles of the intermediate layer.
