Electrolysis of Water Experiment Electrolysis of water experiment is a classic chemical experiment, which is of great significance for understanding the composition of water and the principle of electrolysis. The following is a detailed introduction: Purpose of the experiment Through the method of electrolysis of water, prove that water is composed of hydrogen and oxygen elements; understand the basic principles and processes of electrolysis reaction; observe the electrode [...]

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 [...]
