Hydrogen Electrolyzer Technology

Hydrogen Electrolyzer Technology – AEM Electrolyzer Coatings – Cheersonic

The current hydrogen electrolyzer industry is like “a thousand sails competing, a hundred boats competing for the current”. When alkaline electrolyzers were popular, PEM and AEM technologies had quietly sprouted. Especially AEM technology, it has increasingly shown a trend of latecomers catching up. Following the alkaline electrolyzer and PEM electrolyzer technologies, the pointer of water electrolysis hydrogen production equipment technology seems to have turned to the outlet of AEM electrolyzer.

AEM technology is gaining popularity

AEM technology is also known as “anion exchange membrane water electrolysis hydrogen production technology”. It is an emerging low-temperature water electrolysis hydrogen production technology based on membrane electrode (MEA) design. The advantage of the AEM technology route is that AEM hydrogen production technology started early, and it can be traced back to the 1980s. The reason why hydrogen energy equipment companies are interested in this technology is that the AEM hydrogen production technology of countries around the world is currently at a relatively unified level, and there is no obvious difference in technical iteration in the industry. Hydrogen equipment companies do not have to worry about losing at the starting line.

On the other hand, AEM hydrogen production technology combines the low cost of ALK with the high performance of PEM, allowing AEM electrolyzers to operate in a wider pH range. In addition, the current density of AEM technology can reach 1.5 A/cm² or even higher, which is much higher than the 0.6 A/cm² of PEM technology, which means that at the same power, AEM technology can produce more hydrogen

AEM can also use inexpensive non-precious metal catalysts, such as platinum as a catalyst. This will greatly reduce the system cost of AEM hydrogen production. In addition, this technology has the advantages of zero spacing, high electrical density, and large diaphragm pressure bearing capacity, which greatly improves the stability of the overall hydrogen production equipment. Some hydrogen energy equipment companies believe that AEM hydrogen production efficiency is higher than alkaline, and the current hydrogen production cost of AEM system is almost competitive with the cost of alkaline hydrogen production. With the mass promotion of this technology in the next 3 to 5 years, the purchase cost of AEM system can directly compete with alkaline, because by then, the cost of AEM hydrogen production will be significantly lower than that of alkaline hydrogen production.

Hydrogen production by electrolysis of water is the most advantageous method for producing hydrogen. Utrasonic coating systems are ideal for spraying carbon-based catalyst inks onto electrolyte membranes used for hydrogen generation. This technology can improve the stability and conversion efficiency of the diaphragm in the electrolytic water hydrogen production device. Cheersonic has extensive expertise coating proton exchange membrane electrolyzers, creating uniform, effective coatings possible for electrolysis applications.

Cheersonic ultrasonic coating systems are used in a number of electrolysis coating applications. The high uniformity of catalyst layers and even dispersion of suspended particles results in very high efficiency electrolyzer coatings, either single or double sided.
