ABSTRACT:
A fuel cell comprises at least two cell members, each of which has a flat-plate solid electrolyte having a fuel electrode layer on one surface thereof and an air electrode layer on the other surface thereof, separators, each of which is arranged between the cell members and comprises frame materials and metallic sheets having concave and convex portions and being coupled to the frame materials, a fuel supply path for supplying fuel and an air supply path for supplying air, a fuel discharge path for disharging fuel and an air exhaust path for exhausting air and collector members mounted on the outer sides of the separators of the highest and lowest stages.
Further, another fuel cell comprises at least two cell members, each of which has a flat-plate solid electrolyte layer on one surface thereof and an air electrode layer on the other surface thereof, metallic separators, each of which is arranged between the cell members and comprises a wave-form member, an upper flat-plate member and a lower flat-plate member, the wave-form member being put between the upper flat-plate member and the lower flat-plate member, a hole made in the upper flat-plate member for supplying fuel to the fuel electrode layer and a hole made in the lower flat-plate member for supplying air to the air cell member layer and a fuel supply path for supplying fuel and an air supply path for supplying air.
