<P>PROBLEM TO BE SOLVED: To provide a technique for enhancing introduction efficiency of reaction gas supplied to a fuel cell stack into a fuel cell when the fuel cell stack is composed with the fuel cell formed by arranging a plate on both sides of an MEA and bonding its peripheral part. <P>SOLUTION: The fuel cell 400 is composed by interposing the MEA 410 between an anode side metal plate 420 and a cathode side metal plate 430. The metal plates 420, 430 are almost a rectangular plane shape. The peripheral parts of the metal plates 420, 430 are bonded by interposing the peripheral part of an electrolyte membrane 412 of the MEA 410 between the metal plates 420, 430, and rolling seaming them together. Porous parts 422, 432 are formed in the central part coming in contact with the MEA 410. <P>COPYRIGHT: (C)2008,JPO&INPIT |
