Product Description

Product Description

Perfluorosulfonic acid fuel cell proton membrane DM2256

Fuel cell proton membrane is a solid polymer electrolyte with excellent heat resistance, mechanical properties, electrochemical properties and chemical stability. It can be used under harsh conditions such as strong acids, strong bases, and strong oxidants. Fuel cells prepared by proton membranes can be widely used in passenger cars, commercial vehicles, forklifts, unmanned aerial vehicles, backup power sources, portable generators, cogeneration systems for homes and commercial buildings, etc.

Packaging

1)This product is protected by a back film and supplied in rolls, which facilitates the automated production of membrane electrode assemblies (MEA).

2)The film roll is vacuum-encapsulated in four layers, heat-sealed bag, dust bag, PE bag, and carton from the inside to the outside. The carton can be opened in a normal environment, and the inner packaging must be opened in a clean environment to prevent the film from being contaminated.

Notes

1)The product must be kept in a sealed package before use; once the box is opened, it must be stored in an environment with temperature of 23±5°C and relative humidity of 50±5%, and use it as soon as possible.

2)Store the product away from direct sunlight, heat and dust.
