Membrane electrode of hydrogen fuel cell
Membrane electrode of hydrogen fuel cell

Membrane electrode (MEA), also known as "three in one" or "five in one" module, is the core component of proton exchange membrane fuel cell (PEMFC) and the place of energy conversion in fuel cell. Membrane electrode is responsible for the transport of multiphase materials (including liquid water, hydrogen, oxygen, protons and electrons) in the fuel cell, and converts the chemical energy of fuel hydrogen into electrical energy through electrochemical reaction. The performance and cost of membrane electrode affect and even determine the performance, life and cost of PEMFC. The membrane electrode with high efficiency multiphase transmission capability can greatly improve the performance of PEMFC, reduce the auxiliary equipment consumption of stack system, thus reducing the stack cost and improving the reliability of stack system.
