相对湿度对燃料电池电压衰减影响的渐进分析
Asymptotic analysis of relative humidity effect on voltage decay of fuel cell
摘要
Abstract
To study relative humidity on the influence of the vehicle fuel cell voltage attenuation,a ARH (Anode relative humidity) model was put forward.The calculation model and grid of fuel cell were established.ARH model was transplanted to computational fluid dynamics software (FLUENT),which was used to calculate the fastest single cell voltage attenuation in the cell stack.Finally,the FLUENT model,the ARH model with the experimental data about the tenth cell at the different relative humidity were compared.The results show that ARH model can accurately calculate the 10th single cell (the single cell of the furthest distance from inlet gas port) performance,when the relative humidity is 100％,ARH model precision improve by 10％ than the original model of FLUENT software.Then a new train of thought was provided for the further optimization of the fuel cell stack water management system.关键词
