The rapid depletion in global nonrenewable energy stores has prompted a dramatic increase in both academic and industrial research toward alternate means of energy conversion. Although improbable as a single solution to the problem, fuel cells provide many potential contributions in the form of performance combined with scalability. Fuel cells have demonstrated high levels of power production through the consumption of renewable resources in an easily engineered small scale device that operates under mild conditions and could potentially replace today's ubiquitous batteries. Many evaluate energy conversion devices on the basis of the amount of energy converted per unit volume [energy density (Whr/L)] or per unit mass [specific energy (Whr/kg)]. Fuel cells not only rival battery performance in these terms, but also do not require time-consuming charging and do not suffer from the severe hysteresis effects seen in secondary batteries. However, many of these devices use expensive precious metal catalysts that often limit their commercial viability. Passivation by carbon monoxide or other byproducts causes losses in power production over time, and these devices often require high temperatures and harsh conditions to operate efficiently.Thus, many researchers have looked to nature to assist in our current energy conversion needs. Because of biological versatility and efficiency, organisms are able to convert enormous amounts of energy from an incomparable range of chemical substrates. Many researchers have examined ways of harnessing this ability using biofuel cells. Biofuel cells replace the metal catalyst with a biological catalyst: a microbe, enzyme, or even organelle interacting with an electrode surface. 1-3 These types of catalysts offer great benefits in catalytic activity, specificity, and cost. However, development and full evaluation of these dynamic and often sensitive bioelectrochemical systems require a diverse range of expertise. This article will focus on the current techniques used to evaluate the integrity, kinetics, and performance of enzymatic biofuel cells and the applications of the devices. The techniques described span not only the obvious electroanalytical characterization methods needed to evaluate a power source or analytical device, but also common biological and materials characterization techniques. Enzymatic biofuel cells are in an early stage of development, so new analytical techniques are being employed to understand the advantages and limitations of this technology and the engineering design envelope for applications.

“…After the mitochondria bioanode was dried, it was tested in a traditional biofuel cell test cell with an air breathing cathode. The physical test cell is fabricated as described in ref 12. The air-breathing cathode consisted of Nafion 112 fused together with a gas permeable ELAT electrode with 20% Pt on Vulcan XC-72.…”

“…Glycerol can undergo a 5-step (or 10 electron) oxidation to mesoxalic acid with just the employment of these two enzymes [38]. It is important to note that due to the non-toxic, non-volatile, and improved solvent properties of glycerol, glycerol can be used in 98.9 wt% solutions, where as the other alcohols are all limited to less than 40% due to the swelling of the polymers used to immobilize the enzymes and the stability of the enzymes in the solvent.…”

“…It is important to note that a 5-step oxidation of glycerol to mesoxalic acid results in the use of 86% of the energy density of the glycerol fuel. Therefore, being extremely efficient for such a high energy density fuel [38]. By adding a third enzyme oxalate oxidase, mesoxalic acid can be oxidized to carbon dioxide therefore allowing for the complete oxidation of glycerol [39].…”

Oxidation of Biofuels: Fuel Diversity and Effectiveness of Fuel Oxidation through Multiple Enzyme Cascades

Enzymatic biofuel cells have employed a variety of fuels, including: glucose, fructose, methanol, ethanol, glycerol, lactate, pyruvate and ethylene glycol. This review describes the wealth of fuel diversity in enzymatic biofuel cells, along with the use of multi-enzyme cascades for deep or complete oxidation of biofuels at the anode of enzymatic biofuel cells. Deep or complete oxidation is a relatively new research area for enzymatic biofuel cells, but it is necessary to increase energy density and minimize product inhibition effects.
