Alkaline Electrolyzer
Green hydrogen is the ultimate ideal form of hydrogen energy application. The electrolyzer of its production equipment has become a hot spot in the development of the current hydrogen energy industry. Alkaline electrolyzer (ALK), proton exchange membrane (PEM) electrolyzer, ion exchange membrane (AEM) have been derived ) electrolyzer and solid oxide (SOEC) electrolyzer and other technical routes.
Among them, the alkaline electrolyzer has a development history of more than 60 years, and has the advantages of relatively mature technology, simple structure, safety and stability, and relatively low cost. It is the mainstream application route at this stage. With the explosive growth of green hydrogen projects and the need for large-scale cost reduction, alkaline electrolyzers have started a new round of development towards high hydrogen production, low energy consumption, and fast response.
From the perspective of alkaline electrolyzer materials and cost composition, in addition to relatively simple machined parts such as bipolar plates, end plates, and tensioning screws, the cost of materials such as electrodes, diaphragms, and sealing gaskets is relatively high, and the process is relatively high. Complex, enterprises generally choose external procurement.
Facing the upgrading and development of electrolyzers, the core materials represented by electrodes, diaphragms and sealing gaskets are also preparing for the improvement of technology and process routes:
1. Electrodes can also be called electrocatalysts, which are places where electrochemical reactions occur. Each electrolytic cell has a cathode and an anode electrode, mainly in the form of nickel mesh sprayed Raney nickel, foam nickel, etc. The cost of the electrolytic cell is about Occupying 30%, is also the basis for determining the hydrogen production efficiency of the hydrogen production electrolyzer.
2. In terms of diaphragm, the diaphragm strictly isolates hydrogen and oxygen in the electrolyzer, so the quality of the diaphragm is directly related to the purity of hydrogen and oxygen and power consumption. The current diaphragm products have gone through three generations of development. “Composite diaphragm” is the industry-recognized upgrading and development direction of alkaline electrolytic water diaphragm materials. It has good gas barrier properties, stability, low resistance, and low energy consumption.
3. The sealing gasket solves the insulation problem between the pole piece and the pole piece, which is related to the current efficiency and safety issues. The quality of the insulation performance affects the gas output and stability on the one hand, and on the other hand indirectly determines the pole plate and diaphragm. service life.
Ultrasonic fuel cell catalyst coating systems are uniquely suited for these challenging applications by creating highly uniform, repeatable, and durable coatings.
