The objective of this research was to prepare some strong acids for evaluation by Fort Belvoir as potential fuel cell electrolytes. The major acid, other than phosphoric, H/sup 3/PO/sup 4/, currently under investigation by Fort Belvoir as a fuel cell electrolyte is TFMSA, CF/sup 3/SO/sup 3/H.H/sub 2/O, trifluoromethanesulfonic acid monohydrate aqueous solutions and sodium salt mixtures. TFMSA has been found to be superior to H/sup 3/PO/sup 4/ from the standpoint of electrode kinetics, but certain undesirable characteristics (volatility; wetting of Teflon) led to this research for a better fuel cell electrolyte.
