membrane electrode(MEA)

Release time:2019-04-26 15:59

Summary
Membrane electrode (MEA) is the core component of proton exchange membrane fuel cell (PEMFC). It is the place where chemical energy is converted into electricity. It is the "heart" of fuel cell. It consists of catalyst coating film (CCM) and gas diffusion layer (GDL) on both sides of cathode and anode.


Performance characteristics
High power density, low life and long life.
Ultra-thin and uniform thickness;
It can provide MEA for customers to formulate their needs.
The maximum effective area is 300*500 mm.
