Abstract
In an electrolyte-electrode joined assembly (MEA), a cathode is formed on an intermediate layer stacked on a solid electrolyte. The cathode is a laminate containing at least a first layer facing the intermediate layer and a second layer disposed on the first layer. The first layer contains a perovskite-type composite oxide represented by BaSrCoFeOor LaSrCoFeO. The intermediate layer has an open pore on a surface thereof facing the first layer, and the pore is filled with the first layer.
