PEM燃料电池性能损耗的多场耦合仿真分析
Simulation study on multi-field coupling PEM fuel cell performance loss
摘要
Abstract
The performance of fuel cell was affected by many parameters,such as temperature,humidity,force and electrochemistry.The performance loss of fuel cell was the result of the coupling action of multi physical field.At present,most of the simulation studies do not fully consider these factors,and can not accurately reflect the performance of PEM fuel cells under actual working conditions.Based on the finite element theory,a multi-physics model of proton exchange membrane fuel cell performance was established,the deform structure and contact resistance change caused by assembly tightening force were considered,the fuel cell internal pressure,gas flow field distribution,water distribution and current density distribution condition were simulated and studied.Then a basis in PEMFC multi-field coupling model was provided,thus affected the performance parameter optimization research.关键词
