AEM Porous Transport Layer and Bipolar Plate Porous transport layer (PTL), also known as gas/liquid diffusion layer and current collector, is located between the bipolar plate and the catalyst layer. It mainly plays the role of electrolyte, gas transmission, electron and heat conduction. In PEM electrolyzers, due to the high potential, oxygen-rich and strong acidic environment on the anode side, expensive titanium-based material PTL is often used. In [...]

Research Progress of HER Electrocatalysts Research Progress of HER Electrocatalysts - Catalyst Coating - Cheersonic In recent years, the development of transition metal-based HER electrocatalysts under weak alkaline conditions is still being actively explored. The research on HER electrocatalysts under weak alkaline conditions mainly focuses on non-precious metal elements such as nickel (Ni), cobalt (Co), molybdenum (Mo), copper (Cu), and iron (Fe). Through element doping, alloying, phosphides and [...]

Ultrasonic Spraying for Proton Exchange Membrane Fuel Cell In recent years, Ultrasonic spray coating technology has emerged as a relatively new technique, and it has only been applied in fuel cell applications during this period. Through extensive research and practical experiments, it has been clearly demonstrated that ultrasonic spray coating holds significant value as it represents an effective means to address the crucial issue of reducing platinum loading [...]

Ion exchange membrane (AEM) water electrolysis for hydrogen production AEM is somewhat a hybrid of PEM and traditional separator-based alkaline electrolysis. AEM electrolyzer principle: At the cathode, water is reduced to produce hydrogen and OH–. OH– flows through the separator toward the anode, where it recombines at the anode surface to produce oxygen. Research shows that at 85°C, the current density at 1.8V voltage is 2.7A/cm2. When NiFe [...]

AEM Water Electrolysis Hydrogen Production Technology AEM Water Electrolysis Hydrogen Production Technology - Cheersonic Due to key material technical barriers and manufacturing challenges, AEM water electrolysis technology is still some distance away from large-scale practical application. To this end, combined with the current research status of AEM electrolysis technology, the following prospects are proposed to promote the development and commercialization of AEM electrolysis technology: (1) Developing AEMs with [...]

AEM Electrolyte AEM Electrolytes play an important role in improving the electrolysis efficiency of AEM. Commonly used electrolytes in AEMWE are KOH, K2CO3 and pure water. Different from the high-concentration alkaline electrolyte used in traditional ALK, since the anion exchange membrane can conduct OH−, AEM can use low-concentration alkaline solution, which can avoid safety problems caused by highly corrosive electrolytes during the experiment, not only reducing the cost [...]

AEM Water Electrolysis Catalyst Layer Preparation Process The fabrication of catalyst layers (CL) covers a variety of technical means, such as catalyst spraying (whether in slurry form or other forms), electrodeposition (electroplating, abbreviated ED), thermal decomposition, and screen printing. An ideal catalyst layer should have a large pore surface area to effectively transport reactants and products between multiple active sites of the electrode. Similar to other parts of [...]
