Laboratory investigations were performed to determine the feasibility of the ethanolair biochemical fuel cell system. The direct biocell was found incapable of high electrical energy output. The indirect biocell with buffer electrolyte has shown a ten-fold increase in current density over that of the direct system. The major problem of this biocell system is the incomplete electrochemical oxidation of ethanol. A factorial design plan was used to evaluate kinetics of alcoholic fermentation. Evaluation of results indicated that 1 ethanol can be generated in 1 hour. One per cent ethanol is the minimum fuel concentration required for this system. Author
