Spraying of AEMs

Spraying of AEMs Spraying of AEMs - Ultrasonic Atomization - Cheersonic Currently, the main commercially available water electrolysis technologies are proton exchange membrane (PEM) electrolysis and alkaline electrolysis. However, the acidic environment required in PEM electrolysis limits the choice of catalysts to the expensive noble metals, such as platinum, iridium and it oxides. Furthermore, the Nafion-based PEM and titanium stack components directly increase the capital cost of the [...]

Preparation Technology of PEM Fuel Cell Membrane Electrode

Preparation Technology of PEM Fuel Cell Membrane Electrode Membrane electrode is the site of heterogeneous material transport and electrochemical reaction, which determines the performance, life and cost of proton exchange membrane fuel cells. The membrane electrode and the bipolar plates on both sides constitute the basic unit of the fuel cell—the fuel cell. In practical applications, multiple single cells can be combined into a fuel cell stack according [...]

PEM Water Electrolysis

PEM Water Electrolysis PEM electrolysis of water has a high efficiency of hydrogen production, and is suitable for the volatility of renewable energy power generation. It is the current mainstream and promising electrolysis of water hydrogen production technology. Compared with the alkaline electrolytic cell, the PEM electrolytic cell replaces the asbestos membrane with a proton exchange membrane, conducts protons, and isolates the gas on both sides of the [...]

Operating Principle of PEMFC

Operating Principle of PEMFC Operating Principle of PEMFC - Spraying Fuel Cell Catalyst Inks - Cheersonic Proton exchange membrane fuel cell is also called polymer electrolyte fuel cell. This type of fuel cell mainly relies on a special polymer membrane, on which highly dispersed catalyst particles are coated. This process is called CCM. The structure of PEMFC is mainly composed of proton exchange membrane (electrolyte), catalyst layer, gas [...]

PEM Electrolyzer Advantages

PEM Electrolyzer Advantages PEM Electrolyzer Advantages - PEM Electrolyzer Coating Systems - Cheersonic In a PEM electrolyzer, two electrode compartments are separated by a polymer membrane. Liquid water circulates on the anode side. Electrolysis causes some of the water molecules to split at the anode into oxygen and protons, which pass through the membrane and are reduced to hydrogen at the cathode, which accumulates on the cathode side. [...]
