Background
At present, with the massive use of fossil fuels, the greenhouse effect has become one of the most urgent environmental problems worldwide, and thus a strong demand for new clean energy technologies has arisen. Fuel cells are receiving increasing attention as a clean energy source. Among various types of fuel cells, a Proton Exchange Membrane Fuel Cell (PEMFC) is one of the most promising, and has advantages of high energy conversion efficiency, low operating temperature, availability of various fuels, no noise, zero emission, and the like.
A PEMFC unit is composed of bipolar plates (anode plate and cathode plate) and Membrane Electrode Assemblies (MEA) sandwiched between the bipolar plates sequentially stacked. The MEA is responsible for electrochemical reactions, while the bipolar plates mainly support, collect and separate the fuel and oxidant and direct the reactant to be evenly distributed throughout the electrode while ensuring uniform temperature distribution of the cell during operation and timely discharge of reaction products and waste heat.
The existing research shows that if the flow field of the polar plate is unreasonable in design and has larger flow resistance, the fuel and the oxidant are not supplied uniformly, the water generated by the reaction cannot be discharged timely, the electrochemical reaction can be seriously hindered, and meanwhile, the constant and uniform temperature distribution in the battery is destroyed, so that the performance and the service life of the PEMFC are reduced. Therefore, the flow field design of the polar plate is optimized, so that the flow field of the reactant and the temperature field inside the battery are uniformly distributed, and the method has important significance for ensuring the performance of the PEMFC.
