Description

General description

We are committed to bringing you Greener Alternative Products, which belong to one of the four categories of greener alternatives. Phosphoric acid-doped polybenzimidazole (PBI) membranes offer a cleaner path to energy by enabling high-temperature fuel cells that efficiently convert hydrogen into electricity with low emissions. Their durability and proton conductivity make them ideal for sustainable power systems. Click here for more information.

Application

Phosphoric acid has been used in the preparation of anolyte, a constituent of the capillary isoelectric focusing (CIEF) solutions. It has also been used as a chemical oxidation reagent in flow injection analysis-chemical oxidation-isotope ratio mass spectrometry (FIA-CO-IRMS).

Other Notes

L′acide phosphorique concentré est composé de H₃PO₄ à environ 85 % (aqueux).
