<P>PROBLEM TO BE SOLVED: To provide a fuel cell the power generation efficiency of which can be enhanced by adjusting the flow rate, pressure and direction of a reaction gas flowing from a manifold to a cell thereby maintaining good dry and wet state of a membrane in the cell. <P>SOLUTION: In a fuel cell device 1 which generates power by supplying a fuel gas and an oxidant gas, a gas distribution member 11 having a spiral slit is disposed in a manifold, and a reaction gas flows continuously from the gas distribution member into a cell via the manifold when the gas distribution member is driven to rotate by means of a motor 37 and a rotary member 38. The gas distribution member adjusts the gas flow rate, pressure and direction by adjusting the width and the spiral pitch of the slit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
