Membrane Electrode Assembly Coating
Membrane Electrode Assembly Coating – Ultrasonic Atomizing Coating
Membrane Electrode Assembly (MEA) is the core component of a proton exchange membrane fuel cell (PEMFC). It is a multiphase material transfer and electrochemical reaction site for energy conversion, involving three-phase interface reactions and complex mass and heat transfer processes. Directly determine the performance, life and cost of PEMFC. The structure of MEA mainly includes a gas diffusion layer, a catalytic layer, and a proton exchange membrane. The gas diffusion layer usually includes carbon paper/carbon cloth and a microporous layer supported on it. Generally, the MEA composed of the cathode gas diffusion layer, the cathode catalyst layer, the proton exchange membrane, the anode catalyst layer and the anode gas diffusion layer is called “five in one” MEA. One” MEA. As the most core component of fuel cells, MEA is of great significance to improve its performance and life and reduce costs, which can accelerate the large-scale commercialization of PEMFC. Therefore, the development of MEA with simpler preparation process, more stable performance and lower cost is the main research direction.
