Special Issue Information

Dear Colleagues,

As the global energy structure has transitioned toward cleaner and lower-carbon systems in recent years, hydrogen energy has emerged as a vital component of the new energy paradigm, owing to its high energy density and zero carbon emissions. Against this backdrop, proton-exchange membrane fuel cells and water electrolysis technologies play pivotal roles in hydrogen utilization and green hydrogen production technologies, respectively.

This Special Issue aims to solicit contributions of modeling studies, experimental investigations, and review articles related to proton-exchange membrane fuel cells and electrolyzers. Submissions concerning other types of fuel cell research are also invited.

Topics of interest for publication include, but are not limited to, the following:

  • Multiphysics modeling approaches;
  • Analysis of static and dynamic characteristics;
  • Advanced control methodologies;
  • Emerging catalytic materials;
  • Health state monitoring and fault diagnosis;
  • System integration and optimization;
  • Energy management strategies.

Efficient thermal management is critical for sustaining the performance and durability of Proton Exchange Membrane Fuel Cells (PEMFCs), where excessive operating temperatures accelerate material degradation and reduce power output. Previous studies have explored various cooling channel designs; however, limited research integrates zigzag multi-fin geometries with both computational and experimental validation for fin width optimization under high-velocity cooling. This study presents a combined Computational Fluid Dynamics (CFD) simulation using ANSYS Fluent and experimental investigation of a multi-fin multi-channel cooling system for PEMFCs. The effects of fin widths (0.3–1.0 mm), inlet flow velocities (0.6–3.0 m/s), and cooling media (air, 20% ethylene glycol (EG) solution) were analyzed with respect to cathode surface temperature, power density, and cooling efficiency. Results show that a 0.3 mm fin width with 3.0 m/s inlet velocity reduced the cathode temperature by ~13 K and increased power density by ~40%. The optimized zigzag configuration improved heat transfer uniformity, achieving cooling efficiencies up to 67.0%. Experimental validation confirmed the CFD results with less than 3% deviation. The findings highlight the potential of optimized multi-fin designs to enhance PEMFC thermal stability and electrical output, offering a practical approach for advanced fuel cell thermal management systems.
