Patent ID: 10396369

Abstract:
A fuel cell stack FS includes: a plurality of cell modules M each including an integrally stacked plurality of single cells C; a sealing plate P intervened between each of the plurality of cell modules M; a manifold M3 that penetrates the plurality of cell modules M and the sealing plate(s) P in a stacking direction to distribute reaction gas, wherein the sealing plate P includes a sealing member S4 that surrounds and seals the manifold M3 between the sealing plate P and each of the plurality of cell modules M, and the sealing member S4 includes an extended portion E that extends toward the manifold M3 so that an end face F4 of the extended portion E is flush with an inner wall of the manifold M3. Generated water is suitably discharged through the manifold M3 without a decrease of the flowability of the reaction gas and an increase of the production cost.
