| 摘 要： | 质子交换膜燃料电池(polymer electrolyte fuel cell,PEFC)扩散层(gas diffusion layer,GDL)水管理对其性能十分关键,扩散层可视化研究对指导微观模型的建立,进而指导电池的设计意义重大.搭建了一个离线扩散层可视化研究实验台,通过对不同碳纸进行液态水穿透实验,观测了液态水突破现象,并得到碳纸突破压力随温度近似呈线性变化且成反比.同时通过分析碳纸中传递过程,建立了一种微观模型,通过MATLAB编程计算突破压力大小,并与实验值进行了对比,得到比较一致的结果.

| Abstract: | Water management in gas diffusion layer(GDL) is of great important to the performance of polymer electrolyte fuel cell,meanwhile,visualization of GDL is also meaningful to the build of micromodel for polymer electrolyte fuel cell(PEFC) and then for the design of a more effective fuel cell.An ex-situ visualization set-up for GDL was built.With the experiment on the water breakthrough of GDL,the phenomena were observed and the breakthrough pressure that is approximately linear with and in inverse radio to tem... |
