摘要/Abstract

摘要：

在气体扩散层(GDL)生产过程中,疏水黏合处理和装配压缩变形导致GDL孔隙结构和渗透特性发生变化.首先基于随机重构算法,建立一种添加黏合物质和施加不均匀压缩的GDL建模方法;然后利用格子玻尔兹曼数值仿真气体单相流动,研究黏合物质与压缩形变对燃料电池GDL孔隙结构和气体渗透特性的影响规律.计算结果表明:黏合物质与压缩形变均会导致气体扩散小尺寸孔隙结构占比增大,整体孔隙率减小;GDL的渗透率变化趋势与孔隙率一致,均降低,变化规律基本符合理论预测关系;当孔隙率相近时,压缩变形是导致的渗透率降低的关键因素.

关键词: 气体扩散层, 黏合物质, 压缩变形, 孔隙结构, 渗透率

Abstract:

During the production of gas diffusion layer (GDL), hydrophobic binding treatment and assembly compression lead to changes in pore structure and permeability. In this paper, a GDL model based on stochastic reconstruction is developed with binder and inhomogeneous compression. Single-phase flow of gas is simulated by utilizing the Lattice Boltzmann method and the effect of binder and compression on pore structure and permeability of GDL is explored. The results show that both the binder and the compression cause porosity to decrease and small-scale pore volume to increase, leading to the shrink of permeability. The change is basically consistent with the theoretical relationship between porosity and permeability. Moreover, the decrease of permeability caused by compression is higher than that caused by binder when porosity is similar.

Key words: gas diffusion layer (GDL), binder, compression, pore structure, permeability
