The research was oriented toward the task of developing an improved electrolyte for the hydrocarbon-air fuel cell. A literature study of the properties of organic acids indicated that the following types of compounds warranted investigation: armoatic polycarboxylic acids, perfluoroaliphatic carboxylic acids, mono, di and poly sulfonic acids, and substituted sulfonic acids. This was followed by an experimental program wherein the vapor pressure, wetting characteristics, electrical conductivity, chemical stability, and electrochemical stability of specific compounds were measured. The following compounds (acids) were among those evaluated: dichloroacetic, d1-10-camphor sulfonic, heptafluorobutyric, ethanedisulfonic, sulfosalicyclic, benzenesulfonic, 1,3,6 - napthalene trisulfonic, sulfosuccinic, sulfopropionic, methanedisulfonic, propanesulfonic, methanesulfonic, ethanesulfonic, and sulfoacetic. Most attention was given to the last three acids. The electrochemical behavior of methanesulfonic acid, ethanesulfonic acid, and sulfoacetic acid as fuel cell electrolytes was studied in half cells at various temperatures. The rate of the electro-oxidation of hydrogen at 115 C was very high in methanesulfonic acid and sulfoacetic acids. The rate of the electro-oxidation of propane in methanesulfonic acid and ethanesulfonic acid at 80 C and 115 C was low.
