Sealing structure for fuel cell |
摘要 |
A sealing structure in a fuel cell comprises a pair of separators including gas passages and a membrane electrode assembly held by the pair of separators and having a polymerized electrolytic membrane and a electrode layer so as to form a fuel cell. The sealing structure seals a sealing portion between the pair of the separators and the polymerized electrolytic membrane. A sealing groove is provided to the sealing portion of one of the separators, and a first seal has a thickness greater than the depth of the sealing groove and a portion which is gradually narrowed toward an end thereof. A protrusion is provided to the sealing portion of the other separator, and a second seal having a constant width is provided to the front surface of the protrusion. The polymerized electrolytic membrane is held by the first seal and the second seal.
