<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack which can aim at stabilization of power generation through prevention of flow of water drops into an electrode face of each single cell. <P>SOLUTION: The fuel cell stack is provided with a laminated body 2 with a plurality of unit cells 1 laminated in a thickness direction each constituted by pinching a membrane electrode assembly made by arranging a pair of electrodes on either side of an electrolyte film with a pair of separators. The laminated body 2 is equipped with supply-side communicating holes R1, R2 for supplying reaction gas to the electrodes of each unit cell 1, as well as exhaust-side communicating holes R3, R4 for supplying off-gas from each unit cell 1 penetrating the membrane electrode assembly and the separators in a thickness direction, respectively. The supply-side communicating holes R1, R2 are equipped with heaters 10, 20 as a heating means inside, formed in a sheet shape. <P>COPYRIGHT: (C)2007,JPO&INPIT |
