不同流场的PEMFC性能研究
PEMFC performance research of different flow field
摘要
Abstract
In order to study the output performance of proton exchange membrane fuel cell (PEMFC) under normal temperature in different flow field,a coupling gas passage was improved and two-phase,three-dimensional,multi-component PEMFC model for gas diffusion layer was established.The influence of four kinds of flow field was considered on the output performance of PEMFC.Under the condition that the temperature was set 70 ℃ and the effective area was set 3.61 cm2,it was found that the performance of the single-side interdigital single serpentine flow field was the best,and the single serpentine flow field was the worst.The shape of the anode flow field had little effect on the performance of the PEMFC.The single-side interdigital single serpentine flow field had the most uniform oxygen concentration distribution.The oxygen concentration difference was 6.41 mol/m3.It also had the best drainage performance.The water concentration difference was 10.25 mol/m3 in the cathode flow field.关键词
