Anion Exchange Membrane (AEM) Hydrogen Generator Water Electrolysis Electrolyzer Pure Water

1. Strong large-scale hydrogen production capability: mature technology, single machine power can be made very large, suitable for industrial grade, centralized green hydrogen production
2. Good operational stability: The electrolyte is alkaline solution (KOH/NaOH), the system is stable, and it is not easily affected by impurities and water quality fluctuations
3. Low cost of electrode materials: using non precious metal electrodes (mainly nickel based) avoids the problem of high costs in large-scale applications
4. Long lifespan: Long operating lifespan, suitable for long-term operation in the chemical and power industries
5. Compatible with renewable energy: able to adapt well to fluctuating power sources such as photovoltaics and wind power, but with relatively slow dynamic response speed

1. High purity of hydrogen: Hydrogen purity can reach 99.99%
2. High current density and better efficiency: large hydrogen production per unit area, small footprint
3 .Fast dynamic response: Fast start stop, able to adapt well to fluctuating renewable energy sources such as photovoltaics and wind power
4. Modular and compact in size: The device is compact and suitable for distributed applications or scenarios with limited space
5. High pressure hydrogen production: hydrogen gas above 30 bar can be obtained without additional compression, reducing subsequent costs

1. High cost potential: It can avoid the extensive use of precious metals in PEM while maintaining high efficiency
2. Material friendly: can use low-cost metal catalysts, etc
3. Similar in structure to PEM: with the potential for compact and modular design, it can adapt to distributed hydrogen production
4. Balancing advantages: theoretically combining the low cost of alkaline electrolysis cells with the high performance of PEM
5. Great development potential: has become a research hotspot in recent years, and is expected to reduce the cost of green hydrogen in the future

1. Gas liquid separation system: Separate the gas generated during the electrolysis process from the entrained water mist/droplets, prevent water from being carried in the hydrogen/oxygen gas, ensure the purity of the subsequent hydrogen gas, and prevent electrolyte loss
2. Gas purification system: further remove impurities (water vapor, electrolyte, trace oxygen/hydrogen), ensure hydrogen purity, and output high-purity hydrogen gas
3 .Water and alkali replenishment system: Ensure stable electrolyte concentration and liquid level (mainly for alkaline electrolysis tanks ALK), and pure water replenishment system for PEM electrolysis tanks
4. Hydrogen production power supply: converts alternating current to direct current, provides stable power supply, and ensures electrolysis efficiency
5. Control system: system operation monitoring, start stop control; Real time monitoring of parameters such as pressure, flow rate, temperature, and gas concentration; Safety interlock, explosion-proof protection
6. Pure water machine: provides high-purity water required for electrolysis, avoiding impurities from damaging the electrolytic cell
7. Cooling unit: controls the operating temperature of electrolytic cells, power supplies, gas compressors and other equipment to ensure system safety and extend service life
