The pursuit of carbon neutrality has triggered a third energy revolution focused on renewable energy sources and various types of batteries. Hydrogen energy, as a zero-carbon energy carrier, plays a crucial role in combatting global climate change and decarbonizing the energy system. Proton exchange membrane fuel cells (PEMFCs) are seen as a promising green energy technology due to their efficiency and low emissions. However, factors like kinetic characteristics, power density, and cost limit their performance. In a recent study published in Frontiers in Energy, researchers introduced a 2D topology-curvature optimization method to enhance the design of PEMFCs. By optimizing the flow channel structures of PEMFCs, the method aimed to improve mass transfer and overall fuel cell performance. Through numerical simulations and comparisons with other optimization models, the study revealed that the proposed method significantly enhanced convection and diffusion within the flow field, improving oxygen and water transport. Notably, the optimized TS-III structure showed the highest increases in peak current density and peak power density, with improvements of 4.72% and 3.12%, respectively. The research introduces an efficient way to develop optimized structural models for PEMFCs, potentially reducing design time and costs associated with trial and error. This advancement in PEMFC design could accelerate the integration of hydrogen fuel cells across various applications, furthering the global agenda for carbon neutrality.
