A Membrane Electrode Assembly (MEA) is a critical component in fuel cells and electrolyzers, consisting of an electrolyte membrane sandwiched between two electrodes. It facilitates the electrochemical reactions that convert chemical energy into electrical energy, or vice versa, by allowing ions to pass through while blocking electrons, thus driving the device's operation.
