General description

Nafion™ NR50 is a perfluorosulfonic acid nafion resin that is majorly used as a strong solid acid (H0 -12) with high thermal stability and chemical resistance.

Application

Nafion™ NR50 can be used for a variety of applications such as:
  • a solid acid-catalyst in the synthesis of α-tocopherol
  • a catalyst for cellulose hydrolysis
  • a reference catalyst in the preparation of carbon-based solid acid catalysts

Proton Exchange Membrane (PEM) Fuel Cells

Proton exchange membrane (PEM) fuel cells operate at relatively low temperatures and are composed of two electrodes and a conductive elecrolyte.

Perfluorosulfonic Acid Membranes for Fuel Cell and Electrolyser Applications

Advances in the electrochemical conversion of water to and from hydrogen and oxygen have principally been achieved through the development of new materials and by understanding the mechanisms of the degradation of proton exchange membrane fuel cells (PEMFC) during operation.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
