A fermentation process for the production of ethanol from natural sources, such as corn, comprising introducing a fermentable sugar, an inoculant, and a stabilized chlorine dioxide into a fermentation system is disclosed. The stabilized chlorine dioxide is added preventatively to the fermentation system, at concentrations in the fermentation system of acetic acid no greater than 0.30% (weight/volume) and lactic acid no greater than 0.60% (weight/volume). The stabilized chlorine dioxide is added in an amount effective to substantially prevent growth of bacteria.

A new semi-fuel cell design that incorporates ion exchange membranes to create separate compartments for the anolyte and catholyte to flow through the semi-fuel cell thereby isolating the metal anode of the bipolar electrode from the catholyte while still allowing the necessary ion transfer to affect the necessary electrochemical balance for the reaction to take place in the semi-fuel cell.
