<P>PROBLEM TO BE SOLVED: To provide a fuel cell stack capable of effectively reducing peripheral accessaries, and of improving power generation performance, and having a simple and small structure. <P>SOLUTION: In a fuel cell system 12, a fuel gas depressurized to 0.1-50 kPa from a hydrogen cylinder 88 through a pressure reducing valve 90 is adjusted to 0.0014-0.014 normal l/min in terms of a hydrogen supply quantity per 1 cm<SP>2</SP>of an electrode by a third flow controller 92, and thereafter supplied to this fuel cell stack 10 from a fuel gas supply port 64. Reacting air is pressurized to 0.1-50 kPa through a first blower 80, adjusted to a predetermined air supply quantity by a first flow controller 82, and supplied to the fuel cell stack 10 from a reaction air supply port 60 so as to be always set to 1.5-25 times as much as the hydrogen supply quantity. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
