AI Technical Summary
In the prior art, during the operation of the bipolar plate, the water vapor generated by the reaction is unevenly distributed and the product cannot be discharged effectively in time, resulting in uneven chemical reactions and uneven heat distribution, which causes a drop in the stack efficiency and increases production costs.
A plate structure is designed, including a plate body, air inlet, air outlet, ventilation groove, split column and annular groove. By setting up a diversion column on the ventilation groove, the diversion column on the intake pipeline diverts the gas in the intake pipeline to ensure uniform distribution of the gas; the diversion column on the outflow pipeline drains the gas on the outflow pipeline to facilitate timely discharge of gas.
By evenly distributing the gas, ensure that the gas reacts fully, avoid uneven chemical reactions, improve stack efficiency, and reduce system costs.
