NEPEM N-117W Proton Exchange Membrane for PEMW
Based on specific application scenarios, ThinkreTM proton exchange membranes (PEMs) for water electrolysis hydrogen production are categorized into two series: the 11x Series for industrial hydrogen production and the 11xW Series for hydrogen health applications. Nepem PEMs for water electrolysis feature high conductivity, low gas permeability, and high pressure resistance.
Description
Hydrogen health membrane with high conductivity and low dissolved hydrogen concentration (โค1000ppb).
