Fuel battery bipolar plate

The utility model relates to a fuel battery bipolar plate, which comprises a resin plate body, wherein a fuel flow field and an oxidizing agent flow field are arranged on two lateral surfaces of the resin plate body respectively; through grooves serving as air cooling flow passages are formed in side surfaces of the resin plate body; metal column layers are wrapped in the resin plate body; the fuel flow passage comprises multiple fuel guide launders; a first collection layer is arranged on ribs on two sides of each fuel guide launder; the oxidizing agent flow field comprises multiple oxidizing agent guide launders; a second collection layer is arranged on ribs on two sides of each oxidizing agent launder; the first collection layers and the second collection layers are connected via the metal column layers. Compared with the prior art, resin and metal columns are used for manufacturing the bipolar plate, so that the weight of the bipolar plate is reduced; through grooves are formed in side surfaces of the res
