Experimental study of the influence of dynamic load cycle and operating parameters on the durability of PEMFC

Tiankuo Chu et al.

Summary: The study investigated the impact of different dynamic load cycles on the performance of proton exchange membrane fuel cells, finding that DLC-02 exhibited lower voltage degradation at low current densities, especially in the first 400 hours. The evolution of resistance types and a proposed formula for calculating polarization losses were key findings in distinguishing the sources of voltage loss.

Analysis of surface and interior degradation of gas diffusion layer with accelerated stress tests for polymer electrolyte membrane fuel cell

Minsoo Kang et al.

Summary: The effects of surface and interior degradation of the gas diffusion layer (GDL) on the performance and durability of polymer electrolyte membrane fuel cells (PEMFCs) were investigated using three freeze-thaw accelerated stress tests. The results showed that surface degradation of GDL caused a decrease in capillary pressure, while interior degradation increased mass transport resistance, affecting the performance of the fuel cells.
