Product Introduction Of Membrane Electrolyte:
The water electrolysis membrane we produce can be divided into PEM for industrial hydrogen production and PEM for civilian hydrogen health. The water electrolysis membrane we produce also has the characteristics of high conductivity, low gas permeability, and high pressure resistance. Our production can effectively reduce gas cross-permeation, ensure the purity of hydrogen and the long-term operation stability of the battery.
Product Advantages Of Polymer exchange membrane:
The Membrane electrolyte we produce strictly complies with environmental standards, and all materials used are recyclable, reflecting our commitment and responsibility for environmental protection. The high performance and reliability of the Membrane electrolyte we produce reduce the frequency of maintenance and replacement, thereby reducing long-term operating costs and improving the overall efficiency of the system.

Precautions For Polymer Exchange Membrane:
Environmental considerations: Considering the heat and humidity that may be generated during the electrolysis process, the Water electrolysis membrane should be placed in an appropriate environment with sufficient space and appropriate temperature control.
Emergency measures: Polymer exchange membrane should be clearly marked with emergency stop buttons and leak response procedures to allow operators to respond quickly in an emergency.
Software updates: If the Polymer exchange membrane contains an intelligent electronic control system, please update the software regularly to keep the performance of the Water electrolysis membrane optimized and avoid technical failures.
