摘要： [Problem] To provide a fuel battery cell that can prevent a bonded region between a membrane electrode assembly and a frame from breaking even when surface pressure acts on the membrane electrode assembly of which the periphery is held in the frame. [Means For Solving Problem] A fuel battery cell (1) has a membrane electrode assembly (10), a frame (20), a pair of separators (30), and support members (40). The membrane electrode assembly is formed with an anode (12) and a cathode (13) bonded so as to face an electrolyte membrane (11). 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： In conventional fuel cells that have a structure in which an integrated frame type membrane electrode assembly and a pair of separators have been integrated, the provision of a plurality of protrusions and multi-level sections makes it difficult to achieve miniaturization of the fuel cell. A fuel cell (FC) is provided with a membrane electrode assembly (2) provided with a frame (1), both of which are sandwiched between two separators (3), and is configured such that reactive gas is circulated between the frame (1) and the separators (3). By having a structure in which the frame (1) and both separators (3) each have manifold holes (H1 - H6), and the rims of the manifold holes of frame (1) extend into the manifold holes in the separators (3), and protrusions (11) cover the inner peripheral surfaces of the manifold holes in at least one of the separators (3), it is possible to easily and accurately position and integrate the separators (3) and the frame (1), and fuel cell miniaturization can be achieved because space to position the protrusions (11) is not needed.

摘要： In conventional fuel cells, each of which is provided with a membrane electrode structure having a frame on the circumference thereof, and two separators that sandwich the membrane electrode structure therebetween, contact surface pressure between the membrane electrode structure and the separators is reduced and contact resistance is increased when the separators are brought into contact with both the membrane electrode structure and the frame. Disclosed is a fuel cell (FC), which is provided with a membrane electrode structure (2) having a frame (1), two separators (3, 3) that sandwich the membrane electrode structure therebetween, and gas seals (Gs) between the end portion of the frame (1) and the end portions of respective separators (3), and which has diffuser sections (Da, Dc) for distributing a reacting gas to between the frame (1) and respective separators (3). In the diffuser section (Dc) on the cathode side, the frame (1) is provided with a protruding section (5) in contact with the separator (3), and in the diffuser section (Da) on the anode side, the frame (1) and the separator (3) are disposed by being spaced apart from each other, thereby excellently maintaining contact surface pressure between the membrane electrode structure (2) and the separators (3), and preventing contact resistance from being increased.

摘要： In a conventional fuel battery cell, it is difficult to enhance the durability of a membrane electrode assembly because a bending stress due to a pressure difference between the anode side and the cathode side is concentrated at end portions of the membrane electrode assembly. A fuel battery cell C includes a membrane electrode assembly 2 having a frame 1 in a periphery thereof; two separators 3A, 3B holding them therebetween; and gas seal members 11, 12 provided to peripheral portions of diffuser areas D1, D2 each formed between the frame 1 and one of the separators A, 3B. A diffuser-area-D1-side edge position of the gas seal member 11 in the diffuser area D1 on the cathode side and a diffuser-area-D2-side edge position of the gas seal member 12 in the diffuser area D2 on the anode side are offset from each other in an inside-outside direction of the diffuser areas D1, D2. Thus, a stress occurring due to the gas pressure difference between the cathode side and the anode side is distributed to different sites, and thereby the durability of the frame and the membrane electrode assembly is enhanced.
