A bipolar plate for a fuel cell is provided to realize a small thickness, to prevent easy condensation of humidifying water in a connecting path for flow paths, to minimize power consumption of an air supplying system, and to improve the output of a fuel cell. A bipolar plate for a fuel cell comprises two planar sheets(18,19) adhered to each other, gas flow paths formed on both surfaces of the planar sheets for providing hydrogen flow and air(oxygen) flow separately, and a cooling water flow path formed in the middle of the planar sheets. Each end of the hydrogen flow path(14a), oxygen flow path(14b) and cooling water flow path(14c) is connected to a manifold(15) through a connection path(13) so as to supply hydrogen, oxygen and cooling water, wherein the connection path is formed in the both planar sheets. |
