description The invention discloses a scale bionic fuel cell bipolar plate and a fuel cell, the fuel cell bipolar plate comprises a bipolar plate body, the bipolar plate body is internally provided with a cavity,one end of the bipolar plate body is provided with a gas inlet, the other end of the bipolar plate body is provided with a gas outlet, and the bipolar plate body is internally provided with a plurality of rhombic rib structures; the rhombus rib structures and the cavity form a net-shaped flow channel, and the gas branch inlet and the gas branch outlet are communicated through the net-shaped flowchannel; and every two adjacent rows of rhombus rib structures are arranged in a staggered mode. The obtuse angle of the rhombic rib structures is set as a circular bead, and the meshy air inlet flowchannel with scaly distribution is arranged, so that the turbulence degree of the gas in the flowing process is enhanced, and the reaction gas can more effectively reach the membrane electrode throughthe diffusion layer; namely
