Solid oxide fuel cell and method for producing the same

摘要

An object of the present invention is to provide a fuel cell preventing formation of a diffusion layer containing Ca and other elements, and having an excellent power generation performance at low temperature by preventing breakdown of a crystal structure of an electrolyte by firing. Disclosed is a solid oxide fuel cell which includes an inner electrode, a solid electrolyte, and an outer electrode, each sequentially laminated on the surface of a porous support. The porous support contains forsterite, and has a Ca element content of 0.2 mass % or less in terms of CaO in a surface region at the inner electrode side.
