China's Inner Mongolia Autonomous Region has approved 33 integrated wind-solar hydrogen production projects to scale up green hydrogen production, leveraging its abundant wind and solar resources. Among electrolyzer technologies, Alkaline Electrolytic Cells (ALK) are currently the most mature but have limitations in energy consumption and efficiency. The Proton Exchange Membrane Electrolytic Cell (PEMEC) is highlighted for its advantages in green hydrogen production due to its high current density and compact design. However, PEMECs face challenges in acidic environments and material stability. Researchers are focusing on optimizing the anode flow channels in PEMECs to improve performance. Various innovative designs, inspired by bionic structures and topology optimization, aim to enhance water management, heat transfer, and efficiency. Topology optimization has shown promising results in PEM fuel cells (PEMFCs) by optimizing oxygen concentration, reducing temperatures, and improving cooling efficiency. This dual-objective optimization approach in anode flow channel design for PEMECs presents a significant advancement in improving efficiency and reducing power consumption.
