Gas Diffusion Electrodes (GDEs) are key functional components in hydrogen fuel cell systems, enabling efficient transport of reactant gases to the catalyst layer while supporting electron conduction and product removal. With an optimized porous structure and controlled surface properties, GDEs play a critical role in ensuring stable electrochemical reactions and overall system performance. GDEs are widely used in PEM fuel cell stacks, electrochemical reactors, and research and demonstration systems. Their material structure and durability directly influence gas distribution efficiency, water management, and long-term operational stability of the electrochemical system.

Gas Diffusion Electrodes (GDEs) are essential functional components in electrochemical systems, enabling efficient delivery of reactant gases to the reaction interface while maintaining effective electron transport. Through a carefully engineered porous structure and controlled surface properties, GDEs support uniform gas distribution and stable reaction conditions. In PEM-based systems, GDEs contribute to reliable electrochemical performance by improving mass transport, water management, and operational stability, playing a key role in sustaining consistent system efficiency and long-term durability.
