MEA Preparation Process and Key Quality Control Points In proton exchange membrane (PEM) water electrolysis systems, when it comes to core components, membrane electrode assembly (MEA) is the only one. It integrates catalyst, proton exchange membrane, and gas diffusion layer, and as the only area where electrochemical reactions occur, it directly determines the comprehensive performance, service life, and manufacturing cost of the electrolytic cell. The preparation of MEA [...]

Applications of PI Proton Exchange Membranes Proton exchange membranes, particularly perfluorosulfonic acid (PFSA) proton exchange membranes, are widely used in various fields due to their high proton conductivity, chemical stability, mechanical strength, and low fuel permeability. However, regarding the specific term "PI proton exchange membrane," since PI is not typically used to refer directly to the material of a proton exchange membrane, the following discussion will focus on [...]

Ultrasonic Spray Pyrolysis Coating Equipment Ultrasonic spray pyrolysis coating is an advanced deposition technique used to create thin, uniform, and high-purity films on various substrates. It combines an ultrasonic spray nozzle for atomization with a high-temperature furnace for pyrolysis (thermal decomposition) and synthesis. The core principle is to spray a precursor solution (e.g., metal salts dissolved in a solvent) as a fine, aerosol mist onto a heated substrate. [...]
