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 [...]
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 [...]
Trends in Wearable Medical Devices [Exclusive] 5 major trends in wearable medical devices 01 Health equipment & wearable medical equipment The wearable health device of the past is the wearable medical device of the future In September 2020, Fitbit's ECG application obtained FDA approval and CE mark. The app allows users to spot check signs of atrial fibrillation by themselves. This regulatory milestone appeared about two years after [...]

Some wearable medical devices have made major [...]
Spray-Coated MEA of the DMFC Comparison of Spray-Coated MEA of the DMFC With the advancement of science and technology and the improvement of people's living standards, electronic products such as mobile phones have gradually become necessities in people's lives. These electronic products are becoming more and more abundant and their power consumption is increasing. Due to the limitation of energy density, traditional batteries have been unable to meet [...]
DMFC Performance Optimization Program DMFC Performance Optimization Program - DMFC Coatings - Cheersonic Passive direct methanol fuel cell (DMFC) has a simple structure and has broad application prospects in mobile electronic devices such as mobile phones and PDAs. Improving the performance of membrane electrode (MEA), simplifying the stack structure and realizing pure methanol feed can effectively increase the energy density of the system, which is of great significance [...]
Amorphous Silicon Thin Film Solar Cell Amorphous silicon thin-film solar cell is a kind of solar cell with the best environmental protection performance, which is prepared by using amorphous silicon semiconductor materials on glass, special plastics, ceramics, stainless steel, etc. as substrates. In 1976, Carlson and others of RCA Laboratory in the United States developed amorphous silicon and reported the first amorphous silicon thin-film solar cell, which attracted [...]
Compare Traditional Spraying And Ultrasonic Spraying Compare Traditional Spraying And Ultrasonic Spraying - Cheersonic Blade coating works as follows. The film substrate passes through the coating roller and directly contacts the slurry tank. The excess slurry is coated on the film substrate. When the substrate passes between the coating roller and the doctor blade, the gap between the doctor blade and the substrate determines the thickness of the [...]
Optical Coating Optical and optical components are usually coated with a thin layer of material to change the light reflected or emitted from them. This material is called an optical coating, and it can be used for everything from bulbs and lenses to mirrors and prisms. The main purpose of optical coatings is to block certain wavelengths of light or to provide a highly reflective surface. In some [...]
