ABSTRACT:
A fuel cell stack made from two different ceramic materials which are used to form four distinct layers of each individual fuel cell is provided. The fuel cell stack uses a ceramic ionic conductor to form the electrolyte layer and a ceramic electronic conductor to form an interconnect layer, with the anode and cathode formed from the combination of the electronic and ionic conductor materials. The internally balanced or mirror symmetric configuration eliminates the warpage or camber problems encountered in conventional multilayer cosintering systems, and the use of common materials in adjacent layers enhances bonding across the adjoining interfaces.
