Abstract
The PEMFC internal structure has a very significant impact on the performance of the exchange membrane, and the porosity of the structure is an important part of the fuel cells. Taking the proton exchange membrane fuel cell with four-channel serpentine flow field gradient structure under the working voltage of 0.8 V as an example, the fuel cells under different porosities of 0.750. 0.625, 0.500, 0.375 and 0.250 were simulated and analyzed and the numerical value were compared. The gas flow velocity and the pressure along the flow direction of the distribution were researched. And with the battery output current density as the reference standard, the influence of porosity on the cell output performance was studied.关键词
