Abstract
A solid oxide fuel cell includes an anode layer, an electrolyte layer over a surface of the anode layer, and a cathode layer over a surface of the electrolyte layer. The cathode layer includes a cathode bulk layer, a porous cathode functional layer at an electrolyte, an intermediate cathode layer partitioning the cathode bulk layer and the porous cathode functional layer, the porous intermediate cathode layer having a porosity greater than that of the cathode bulk layer. The solid oxide fuel cells can be combined to form subassemblies that are bonded together to form solid oxide fuel cell assemblies.
