High-temperature proton exchange merane fuel cells (HT-PEMFCs) utilize a phosphoric acid- (PA-) doped polybenzimidazole (PBI) merane as a polymer electrolyte. The PA concentration in the merane can affect fuel cell performance, as a significant amount of PA can leak from the merane electrode assely (MEA) by dissolution in discharged water, which is a byproduct of cell operation

A mineral acid that goes by the formula H3PO4. This formula specifically refers to orthophosphoric acid, but orthophosphoric acids easily coine with themselves to create compounds referred to as phosphoric acids, generally. Typically used as a chemical reagent, the acid is a very polar molecule, meaning it is extremely water soluble. In food usage, the additive is used to acidify foods and

10% concentration. Phosphoric acid is said to be tasteless while lactic in large quantities can potentially leave flavor. Being a lower conentration than the Lactic, it is slower to change the pH of your water and therefore more forgiving to use. BEST ANSWER: The bottle does come with a printed label that has the product information.
