摘要： A fuel battery cell has a membrane electrode assembly, a frame, a pair of separators, and support members. The membrane electrode assembly is formed with an anode and a cathode bonded so as to face an electrolyte membrane. The frame holds the periphery of the membrane electrode assembly. The pair of separators sandwich the frame holding the membrane electrode assembly. The support members protrude along an edge part of the frame so as to pass beyond the frame and support the membrane electrode assembly.

摘要： A fuel cell stack has at least two cell modules, each of which includes an integrally-stacked plurality of fuel-cell single cells, and a sealing plate interposed between the cell modules. The sealing plate comprises a sealing member that seals an interface between the sealing plate and an edge part of the cell modules. The fuel cell stack further comprises a member contacting structure that transfers a load in a stacking direction, disposed in a sealed inner area between the cell modules and the sealing plate. Each of the plurality of fuel-cell single cells has a membrane electrode assembly and a pair of separators that sandwich the membrane electrode assembly. The member contacting structure allows the outermost separators of the adjacent cell modules to face each other so as to transfer a load in the stacking direction.

摘要： A fuel cell stack is constituted by stacking fuel cells including a membrane electrode assembly constituted by sandwiching an electrolyte membrane with a pair of electrodes and a pair of separators that have flow passages through which gas to be supplied to the membrane electrode assembly flows, the pair of separators being arranged across the membrane electrode assembly. The fuel cell stack includes a welded portion where the separators adjacent to one another in a stacking direction of the fuel cell are welded. The separator in the stacking direction at the welded portion has a height lower than a height of the separator other than the welded portion.
