基于气体扩散层接触压力均一性的质子交换膜燃料电池封装载荷优化研究
Study of PEMFC package load optimisation based on GDL contact pressure homogeneity
摘要
Abstract
This paper establishes a three-dimensional finite element model of proton exchange membrane fuel cell(PEMFC)to investigate the impact of fuel cell packaging loads on the uniformity of gas diffusion layer(GDL)contact pressure.The coefficient of variation(CV)is employed to measure the uniformity of GDL contact pressure,with the objective of minimizing CV.Support vector machines(SVM),backpropagation neural networks,and particle swarm optimization algorithms to optimize the SVM.The gray wolf optimization algorithm was then employed to optimize the packaging load,using the best surrogate model as the fitness function within the optimization algorithm.The results indicate that compared with the other three methods,the surrogate model established using the particle swarm optimization algorithm to optimize the support vector machine achieves higher prediction accuracy.Compared with the pre-optimization stage,the CV decreased by 35%,contact pressure uniformity improved,and both the reliability and service life of the fuel cell were enhanced.关键词
