Product Information of Proton exchange membrane electrolysis:
By incorporating ePTFE (expanded polytetrafluoroethylene) microporous reinforced material into the traditional polymer electrolyte membrane vs proton exchange membrane, we achieve high strength, excellent conductivity, and low ion permeability. ProtoneX's PEM for hydrogen fuel cell membranes has been demonstrated in both laboratory settings and the market to be comparable to similar products from Gore.
Product Advantages of Proton exchange membrane electrolysis:
1. The Solid polymer electrolytes we produce exhibit stable electrochemical performance during the operation of the battery, ensuring the reliability and consistency of the battery.
2. The Solid polymer electrolytes we produce can be used in combination with renewable energy to improve energy utilization efficiency and support sustainable energy development.
3. The Solid state electrolyte materials we produce can be applied to modularly designed battery systems, which facilitates system expansion and maintenance and improves the flexibility and operability of the overall system.

Transportation of Proton exchange membrane electrolysis:
Transportation environment: Keep the transportation environment dry and avoid the impact of high humidity on the Solid state electrolyte materials.
Anti-shock measures: Avoid severe vibration and impact during transportation, and use shock-absorbing measures (such as suspension system or air cushion).
Stacking method: Avoid stacking too high during transportation to prevent the lower packaging from being compressed and deformed.
Transportation method: Choose a suitable transportation method (such as air, sea or land transportation) according to the transportation distance and time, and ensure that the transportation time is as short as possible to reduce the impact of environmental changes on the film.
Notes of Proton exchange membrane electrolysis:
During operation, control the current density within the design range to avoid excessive current density causing local overheating and aging of the Solid polymer electrolyte.
Unused proton exchange membranes should be stored in a dry, light-proof and sealed environment to avoid the effects of high temperature and humidity on the Solid polymer electrolyte.
Regularly check the operating status of the fuel cell system to ensure that the Solid state electrolyte material has no signs of damage or performance degradation.
