Membrane Electrode Assembly

Membrane Electrode Assembly
Find and compare membrane electrode assemblies (MEA) from leading B2B suppliers with technical specifications. A Membrane Electrode Assembly (MEA) is the heart of PEM fuel cells and PEM electrolyzers, where electrochemical reactions take place to convert hydrogen into electricity—or vice versa. MEAs consist of a proton exchange membrane sandwiched between catalyst-coated electrodes, often integrated with gas diffusion layers. In the hydrogen industry, MEAs are critical for achieving high efficiency, durability, and performance in fuel cell vehicles, stationary systems, and water electrolysis units. Their quality directly influences power output, hydrogen consumption, and operating life. Key selection criteria include membrane thickness, catalyst loading, ionic conductivity, gas permeability, and compatibility with the intended system configuration and operating conditions.
