Fuel cell bipolar plate of bionic flow field

The invention provides a fuel cell bipolar plate of a bionic flow field, the fuel cell bipolar plate comprises a bipolar plate body, the bipolar plate body is formed by overlapping a cathode plate, a catalytic diffusion layer and an anode plate, the cathode plate and the anode plate are both provided with a gas inlet area, a front end diffusion transition area, a reaction area, a rear end diffusion transition area and an outlet area, and gas passes through the gas inlet area, the front end diffusion transition area, the reaction area, the rear end diffusion transition area and the outlet area in sequence. The front end diffusion transition area is provided with a bionic leaf bifurcated flow channel, the front end of the bionic leaf bifurcated flow channel is provided with a flow adjusting groove, and the power rotating mechanism rotates to drive an adjusting piece to rotate so as to adjust the unit flow of gas entering the front end diffusion transition area. According to the invention, the flow of gas enteri
