<P>PROBLEM TO BE SOLVED: To enable to surely let condensed water directly fall in a gravity direction along a reaction gas communicating hole, and to stop generation of liquid junction between power generating cells. <P>SOLUTION: The fuel cell stack 10 has a plurality of power generating cells 12 laminated in a gravity direction. With a cathode-side separator 24 as a constituent of the power generating cell 12, an oxidizer gas exhaust communicating hole 28b is communicated with an oxidizer gas flow channel 36, and at the same time, the former 28b has a water guide member 52 provided for letting condensed water fall down directly in a gravity direction along it 28b. The water guide member 52 is structured of a plate member protruded inside the oxidizer gas exhaust communicating hole 28b and yet slanted toward a gravity direction. <P>COPYRIGHT: (C)2010,JPO&INPIT |
