In this final report early experiments on a variety of organic acids used as fuel cell electrolytes are summarized. The selection of tetrafluoroethanedisulfonic acid TFEDSA is reviewed and an improved synthesis for the acid is presented. Fuel cell data using high surface area polytetrafluoroethylene bonded platinum black electrodes is given for phosphoric acid, organic acid-phosphoric acid mixtures and TFEDSA electrolytes. For the latter a variety of paraffinic fuels randing from ethane to pentane have been explored and polarization data is presented. Endurance data extending to 400 hours is given for propane and butane fuels. Levels of performance are similar to results obtained with direct propane oxidation in phosphoric acid.
