ABSTRACT:
A solid electrolyte fuel cell having a multi-layer structure of flat unit cells composed of a solid electrolyte, a first electrode and a second electrode with metal bipolar plates as gas barriers and collectors preferably made of foam metal or a foam alloy interposed between the adjacent unit cells. A fuel gas and an oxidizing gas are supplied to the fuel cell so that they flow in the directions crossing each other with the solid electrolyte interposed therebetween. The metal bipolar plate is preferably provided with grooves so that the fuel gas and the oxidizing gas can be uniformly distributed over the plate.
