Problems solved by technology

However, due to the relatively small size of the gas inlet, the distribution of gas in the flow channel far away from the gas inlet is relatively small, and the uniform distribution of gas in each flow channel on the bipolar plate is difficult to be guaranteed.

Abstract

The invention discloses a proton exchange membrane fuel cell bipolar plate distributing head and a design method thereof. The proton exchange membrane fuel cell bipolar plate distributing head comprises an air inlet and a diversion area, wherein one end of the diversion area is connected with the air inlet, the other end of the diversion area is connected with a runner of a bipolar plate, the diversion area comprises multiple diversion strips which are in Z-shape arrangement, and the air inlet direction of the air inlet is consistent to the extending direction of the runner. The diversion strips in Z-shape arrangement are embedded in the proton exchange membrane fuel cell bipolar plate distributing head, so airflow distribution uniformity in each channel of a proton exchange membrane fuel cell is improved, thus being beneficial to improving the performance of the proton exchange membrane fuel cell.

Description

technical field [0001] The invention relates to the technical field of proton exchange membrane fuel cells, in particular to a bipolar plate distribution head of a proton exchange membrane fuel cell and a design method thereof. Background technique [0002] Proton exchange membrane fuel cell (PEMFC) is considered as an ideal power source suitable for human development and environmental requirements due to its high efficiency, high specific energy, low pollution and other advantages. Among them, the bipolar plate is an important part of PEMFC. There are flow channels processed on both sides of it, which play the role of distributing reaction gas, collecting current, mechanical support, water and heat management, and separating reaction gas between cathode and anode. Reasonably designed bipolar plate structure can improve the uniformity of reaction gas distribution in the flow channel, so that sufficient reaction gas can be obtained everywhere in the membrane electrode, and th...
