The present invention belongs to the technical field of
fuel cells, and discloses a bipolar plate with a harp-shaped flow field structure in a
liquid fuel cell and a design method. The flow channel structure of the fuel
cell adopts the bionic principle, and uses the
body shape of a harp-shaped creature to make the flow channels of the
anode and
cathode plates, so that the fuel and oxidant of the fuel
cell are in contact with the membrane
electrode over a large area, stabilize the flow of the fuel and oxidant in the flow channel, reduce the flow resistance of the fuel and oxidant in the flow channel, increase the pressure drop, and make the fuel and oxidant evenly distributed on the surface of the membrane
electrode. The present invention can solve the problem of improving the performance of
fuel cells from a technical principle, provide theoretical and
technical support for the commercial application of
fuel cells, and accelerate the commercial application of fuel cells. The present invention reduces the flow resistance of the fuel and oxidant in the flow channel, reasonably increases the pressure drop, and promotes the uniform distribution of the fuel and oxidant on the surface of the
electrode, thereby improving the performance of the battery.
