Abstract : Laboratory investigations were performed to determine the feasibility of the ethanol/air 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)
