Hydrogen Energy Electrode Assembly

• 5-layer MEA: The 5-layer MEA is the most widely used type due to its balance of performance and cost-effectiveness. It typically consists of an anode, cathode, and two ion exchange membranes. This configuration allows for efficient proton conduction and effective gas diffusion, making it suitable for various applications, including fuel cell vehicles and portable power systems. Research has shown that 5-layer MEAs can provide improved performance under different operating conditions, making them a preferred choice in the industry.
• 7-layer MEA: The 7-layer MEA incorporates additional layers that enhance performance and durability. This design usually includes extra catalyst and membrane layers, which can improve the overall efficiency of the fuel cell. These MEAs are often used in high-performance applications where maximum power output and longevity are critical. Studies indicate that the 7-layer configuration can achieve higher current densities and lower degradation rates compared to simpler designs, making them suitable for demanding environments such as heavy-duty transport and stationary power generation.
• 3-layer MEA: The 3-layer MEA is primarily used in applications where cost reduction is a priority. While this type may not provide the same level of performance as 5-layer or 7-layer configurations, it can still be effective for specific low-power applications. This design typically includes fewer catalyst layers and is more suitable for small-scale devices or applications where weight and cost are significant factors.
