阴阳极非对称增湿耦合温度对PEMFC水传输及性能的影响
Influence of Asymmetric Anode and Cathode Humidification Coupled Temperature on Water Transport and Performance of PEMFC
摘要
Abstract
To investigate the effects of operating temperature and asymmetric anode-cathode humidification on proton transport and performance of proton exchange membrane fuel cells(PEMFCs),this paper develops a proton transmembrane transport(PTT)model,which is coupled with COMSOL for multiphysics simulations.Experiments and simulations are conducted on a self-built fuel cell platform at 50,60,and 70℃under different anode humidity conditions to examine cell performance,transmembrane water flux,membrane water content,and proton conductivity.The results show good agreement between the PTT model and experimental data,with a maximum relative error below 9%and the highest accuracy at 60℃.Temperature and anode humidity jointly affect cell performance:75%anode relative humidity is optimal at 50 and 60℃,whereas 100%is more favorable at 70℃.As anode humidity increases and cell voltage decreases,transmembrane water flux,membrane water content,and proton conductivity generally increase,but slightly decline at 70℃because of enhanced membrane water evaporation.These findings indicate that anode humidity should be optimized with operating temperature to balance membrane hydration,water transport,and cell performance,providing guidance for PEMFC water management and parameter optimization.关键词
