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.

A fuel cell (C) in a fuel cell stack (FS) is provided with a gas seal projection (92A) and a coolant seal projection (92B) projecting from at least one of two separators (30, 40) toward a membrane electrode assembly. The gas seal projection (92A) and the coolant seal projection (92B) are provided with recesses (33a) serving as coolant passages (80) on the side opposite to the membrane electrode assembly. At least one of the gas seal projection (92A) and the coolant seal projection (92B) is provided with a resistance portion (50) for suppressing a flow of a coolant out of a power generation portion cooling portion (84).
摘要:
This insulating structure is for a fuel cell stack or a fuel cell of the fuel cell stack. The fuel cell stack includes a membrane electrode assembly with a peripheral frame and a pair of separators that hold the frame and the membrane electrode assembly in between and is formed by stacking a plurality of sets of the membrane electrode assembly and the pair of separators. The insulating structure includes: a coupling member disposed on at least a part of an outer periphery of the fuel cell stack or the fuel cell; and a projection formed on the coupling member in an area surrounded by the pair of separators and the frame.
