摘要
以质子交换膜（PEM）燃料电池气体扩散层（GDL）为对象
基于Comsol建立考虑催化层复杂结构的球形催化剂团簇模型
通过数值模拟和实验验证的方法探究GDL形变与性能之间的关系。结果表明：当封装载荷小于0.6 MPa时
接触电阻降低对电池所带来的正效应占主导地位
接触电阻计算结果与实验值最大误差为1.7%;封装力较大时
GDL 孔隙率降低所带来的负效应占主导地位
且封装载荷对液态水饱和度分布影响较大;GDL形变量为27.2%时电池输出功率最大。
Abstract
The gas diffusion layer （GDL） of proton exchange membrane （PEM） fuel cell was taken as the research object
and a spherical catalyst cluster model considering the complex structure of the catalyst layer was established based on Comsol. The relationship between GDL deformation and performance was investigated by numerical simulation and experimental verification. The results show that when the packaging load is less than 0.6 MPa
the positive effect of contact resistance reduction on the battery is dominant
and the maximum error between the contact resistance calculated value and the experimental value is 1.7%
which meets the accuracy requirements. When the encapsulation force is large
the negative effect caused by the decrease of GDL porosity is dominant
and the encapsulation load has a great influence on the distribution of liquid water saturation. When the GDL shape variable is 27.2%
the battery output power is maximum.
