Proton Exchange Membrane Electrolyzer
Advantage of PEM Electrolyzer
Dynamic | Efficient | Clean
PEM gets its name from the proton exchange membrane. PEM is characterized by allowing protons to permeate, but not gases such as hydrogen or oxygen. Therefore, during the electrolysis process, the membrane in particular has the function of a separator, preventing the generated gas from mixing. The front and back of the film are electrodes connected to the positive and negative terminals of the power supply. Breaking up water molecules at the electrodes. Compared to traditional alkaline electrolysis, highly dynamic PEM technology is well suited for harvesting the unstable energy generated by wind and solar power.
In addition, PEM electrolysis also has the following characteristics:
- The higher the power density, the higher the efficiency
- High quality gas generation even under partial load · Low maintenance and reliable operation
- No chemicals or impurities
-

Proton exchange membrane hydrolysis tank (PEM)
The new model for PEM hydro-electrolysis in the HyjadeChain, is a new and powerful product line in the current PEM electrolysis portfolio over 10 MW. The modular design of the HY-H300 makes unique use of the scaling effect, thus significantly reducing the investment costs. Due to high equipment efficiency and availability, optimized solutions can significantly reduce hydrogen production costs.
The product has the following advantages:
- With a high level of efficiency and extraordinary dynamic performance, it has competitive prices and low maintenance requirements;
- No hazardous substances;
- Only high quality, high purity hydrogen is produced.
- Product introduction
HyjadeChain recommends that the production capacity of the latest series of hydrogen generators is 0.01Nm3 /h ~ 300Nm3/h. PEM type hydrogen generator uses pure water as electrolyte, less pollution, non-corrosive, high hydrogen purity. Compared with alkaline hydrogen generators, it can operate in the range of 0 to 10096 with a fast response speed, with higher current density and electrolytic efficiency (up to 85b). Thus, the electrolytic cell can be lightweight, land free and operation free adjustment.
- The first megawatt PEM hydrogen production system running
In September 2020, the first megawatt and PEM electrolytic water hydrogen production project realized system construction and acceptance. The system has been in operation for one month, the electrolytic power of the system has reached 1.3MW, the hydrogen production rate is 260Nm³/h, 0-150% adjustable, the hydrogen production purity is 99.9995%, the outlet hydrogen pressure is 3.8MPa, and the hydrogen supply can be achieved in 5 minutes. At present, the system is the first megawatt-level PEM hydrogen production system in China, and the hydrogen production scale can meet the application of hydrogen production energy storage, hydrogen refueling station and other fields.
