Difficulties in Commercializing AEM

Difficulties in Commercializing AEM – Fuel Cell Catalyst Coatings – Cheersonic

Although AEM’s water electrolysis hydrogen production technology has made significant progress and a number of new AEM products have been released, AEM has not yet entered large-scale commercialization.

First of all, the biggest challenge facing AEM technology lies in its technical verification. Currently, AEM technology still needs to be verified in actual operation, rather than just staying at the proof-of-concept or small-scale demonstration stage. In the short term, demonstration projects in off-grid scenarios are the most suitable development stage for AEM technology. This mainly involves two aspects of verification: one is the limit of the ability to adapt to new energy fluctuations; the other is the operating life and stability, that is, how many hours the AEM system can operate in real new energy scenarios, and when significant performance will appear. attenuation.

It is well known that membrane material is a key factor affecting the life of AEM stack, but it is not the only factor. The overall design of the battery stack, the selection and flow channel optimization of the bipolar plate, the ratio, design and selection optimization of the anode and cathode catalysts, the balance optimization of the mechanical properties and life of the membrane, the spraying and packaging of the membrane electrode, etc. are all Important factors affecting the comprehensive performance of AEM fuel cell stack. In view of the current state of precision of domestic mechanical processing equipment, it is also necessary to reversely optimize the assembly precision from the source of the battery stack design.

From the perspective of commercialization difficulties, in addition to the issue of hydrogen production, the life and stability of the AEM system are also two major challenges. In the green electricity scenario, the hydrogen production system faces the problems of frequent start and stop and large power fluctuations. Currently, AEM technology can provide excellent volatility hedging performance at a price lower than PEM, but the system life is relatively short. In fact, the lifespan of both AEM and PEM does not meet the basic requirements for commercialization, which is a difficult problem that global AEM manufacturers need to work together to overcome. Of course, this problem can also be solved through engineering means, such as arranging a hybrid water electrolysis system (PEM+ALK or AEM+ALK) through artificial intelligence scheduling to alleviate the current difficulties.

Currently, AEM’s global supply chain system is still in its early stages. Whether it is the manufacturer of core materials or the manufacturer of BOP (auxiliary equipment), their professionalism needs to be greatly improved. The AEM industry needs more participants to join in and jointly improve the maturity of the supply chain and the competitiveness of the final products.

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.
