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 FS includes: a stack A that includes a single cells C that are stacked, each of the single cells including a frame 2 that holds an outer periphery of a membrane electrode assembly 1 and a pair of separators 3, 4 sandwiching the membrane electrode assembly 1 and the frame 2; and a case 50 that houses the stack A. The frame 2 comprises a protrusion 11 that protrudes outward from an outer periphery of a frame body 2A beyond an outer peripheral edge of the pair of separators 3, 4. A protrusion length of the protrusion 11 is greater than at least a gap between the frame 2 and one of the pair of separators 3, 4, and the protrusion 11 is bendable with respect to the frame body 2A. The protrusions prevent a contact between the separators 3, 4 of the single cell C and a contact between the end faces of the separators 3, 4 and the case 50 so as to prevent a short circuit of the single cell C.

摘要： A cell structure for a fuel cell stack that is formed by stacking unit cells C each including a membrane electrode assembly 1 and a pair of separators 2 holding the membrane electrode assembly 1 therebetween. The membrane electrode assembly 1 includes a frame 3 in the periphery having such a size as to extend outward over the edges of the separators 2. Communication holes 21, 22 in communication with the front and back sides are formed in the frame 3 in an area from a sealing part 11 between frames 3 adjacent in the cell stacking direction to a sealing parts 12 between the membrane electrode assembly 1 and the separators 2. The air in a space Q formed between the inner and outer sealing parts 11, 12 is allowed to be released to the outside through the communication holes 21, 22, and a breakage of the adhesive of the sealing parts 11, 12 is thereby prevented.

摘要： The fuel cell stack FS includes; a stacked plurality of single cells C each including a frame 1 of a membrane electrode assembly 2 and a pair of separators 3, 4; and a sealing member 6 disposed between the plurality of single cells C. The pair of separators 3, 4 include respective supporting portions 9, 10 that are in contact with the frame 1, and the sealing member 6 is disposed on one supporting member 10. Further, the supporting portions 9, 10 of the separators 3, 4 have different sizes so that an overlapped portion W is formed in which a base surface 7 where the supporting portion 9 of one separator 3 is in contact with the frame 1 is overlapped with a top surface 8 where the supporting portion 10 of the other separator 4 is in contact with the frame 1 in the stacking direction. The overlapped portion W receives and transmits reaction force of the sealing member 6 between the single cells, which prevents narrowing of gas channels or decrease of the sealing surface pressure.
