PEM Fuel Cell
Proton exchange membrane fuel cell (proton exchange membrane fuel cell, PEM fuel cell or PEMFC for short)
The PEM fuel cell contains a membrane electrode assembly (membrane electrode assembly, MEA for short), which is composed of a gas diffusion layer, electrodes and polymer electrolyte membranes. An electrochemical reaction takes place in the MEA to generate electricity.
Membrane electrode is the place of multiphase material transport and electrochemical reaction, which determines the performance, life and cost of proton exchange membrane fuel cell. The membrane electrode and the bipolar plates on both sides form the basic unit of the fuel cell-a single fuel cell. In practical applications, multiple single cells can be combined into a fuel cell stack to meet the needs of different sizes of power output according to the needs of the design.
MEA structure design and optimization, material selection and optimization of preparation process have always been the key technology of PEMFC research. In the development process of PEMFC, membrane electrode technology has undergone several generations of innovations, which can be roughly divided into three types: hot pressing method, CCM method and ordered membrane electrode.
Cheersonic’s unique ultrasonic spray technology delivers efficient, stable and precision coating, which improves the catalyst utilization and improves the three-dimensionality. Designed for sprayingPEM, GDL, Electrode and electrolyte materials, as well as carbon black ink suspension, PTFE binder, ceramic slurry, platinum, platinum and other expensive metal catalysts. The standing model can meet the needs of R&D.
