Microstructures and electrical conductivity properties of compressed gas diffusion layers using X-ray tomography

Lingfeng Ye et al.

Summary: This study investigates the bulk resistances of commonly used commercial GDLs (carbon paper and carbon felt) during the compression process from the perspective of microstructure mechanisms. The results show that the arrangement of fibers becomes more compact during compression, leading to a rapid decline in bulk resistivity. Additionally, the fiber density and tortuosity also affect the bulk resistivity of GDLs.

Full-scale three-dimensional simulation of air-cooled proton exchange membrane fuel cell stack: Temperature spatial variation and comprehensive validation

Guobin Zhang et al.

Summary: This study conducted a full-scale stack three-dimensional simulation for proton exchange membrane (PEM) fuel cell and investigated the temperature distribution, cell/stack performance, and impact of air cooling. The research found that there are significant temperature differences between the fuel cells on the two sides and in the middle, and that higher temperature sites have lower oxygen content due to increased water vapor concentration. It was also found that increasing the cooling air flow rate decreases stack temperature and reduces temperature variation, thus benefiting the uniform distribution of gases in the stack.

Application of self-adaptive temperature recognition in cold-start of an air-cooled proton exchange membrane fuel cell stack

Xianxian Yu et al.

Summary: Self-adaptive temperature control is crucial for the successful cold-start of air-cooled PEMFC, and this paper analyzes the temperature distribution characteristics during the cold-start process based on adaptive temperature recognition control. Preheating and cold-start models are established to explore the optimal balance between hot air flow rate and temperature for a uniform temperature distribution. The results show that the air-cooled PEMFC stack can be successfully started up at -40 degrees C within 10 minutes using external gas heating.

Impact of gas diffusion layer spatial variation properties on water management and performance of PEM fuel cells

Xiao Ma et al.

Summary: The study reveals that spatial variation in porosity and wettability distribution in gas diffusion layer can affect liquid water saturation profile, fuel cell performance, and membrane water content. Higher operating pressure improves performance, while increased anode inlet humidity results in higher membrane water content. The wettability distribution also plays a role in water management and performance of fuel cells, though its influence is more indirect than porosity.

Pore-scale modeling of gas diffusion layers: Effects of compression on transport properties

Lijun Zhu et al.

Summary: A pore-scale simulation approach combining PSM and LBM was developed for studying the effects of mechanical compression on gas diffusion layer of a proton exchange membrane fuel cell. It was found that compressing the GDL led to increased electric and thermal conductivities, but decreased gas diffusivity and water permeability. The in-plane transport properties were greater than the through-plane properties, with anisotropy decreasing with higher compression ratios. The study also showed that compression affected the local current density and diffusion limitations in cell performance.
