3D Computational Analysis of Single Channel HT-PEMFCs: Enhancing Efficiency and Durability

This paper presents an integrated 3D computational model for analysing high-temperature polymer electrolyte membrane fuel cells (HT-PEMFCs), focusing on the interactions within the system's components and processes. Developed using COMSOL software, the model incorporates key physical phenomena such as mass transport, electrokinetic, and heat transfer. By simulating various operating conditions and material properties, this study provides insights into the influence of parameters like operating pressures, gas diffusion layer porosity, anode stoichiometry, cathode stoichiometry, and membrane conductivity on fuel cell performance. The aim is to enhance understanding of HT-PEMFC operation and guide the development of more efficient and durable fuel cells.
