摘要
为了优化、提升质子交换膜燃料电池的传热性能,通过优化流道的结构设计来提高热交换率.为了验证结构对燃料电池传热的影响,基于有限体积法建立燃料电池传热模型进行仿真.仿真结果表明,冷却流道的分布过于集中和过于稀疏都会带来问题:过于集中时,横向温度不均匀性更严重;过于稀疏时,高度方向温度梯度更大,可能带来额外的热应力.
In order to optimize the heat transfer performance of the Proton Exchange Membrane Fuel Cell,the heat exchange rate is improved by optimizing the structure design of the flow channel.In order to verify the influence of the structure on the heat transfer of the fuel cell,a fuel cell heat transfer model was established based on the finite volume method for simulation.Simulation results show that too concentrated and too sparse distribution of cooling runners will cause problems:when it is too concentrated,the lateral temperature unevenness is more serious;when it is too sparse,the temperature gradient in the height direction is greater,which may bring additional thermal stress.
