“…Although the electric power generation demonstrated in this study was lower than those reported by several authors, such as by Zebda et al [18,19], our results clearly demonstrated that enzyme fuel cells employing FADGDH are capable of generating electric power utilizing variety of cellulolytic sugars as the substrate, including glucose. Thanks to the direct electron transfer capability of the enzyme, simple structure and component of enzyme electrode was achieved, consequently allowed to utilize cost effective and versatile carbon cloth as the electrode materials.…”

An enzyme fuel cell employing a carbon cloth electrode and bacterial FAD dependent glucose dehydrogenase (FADGDH) based on the direct electron transfer principle was constructed, and its scalability and cellulolytic sugar conversion were investigated. FADGDH was immobilized on the carbon cloth electrode together with carbon paste to form a multi-module type enzyme fuel cell by combining platinum-supported carbon immobilized carbon cloth as the cathode. The enzyme fuel cell was stable for more than 7 days of continuous operation. The 3 3 module (18 cm 2 ) enzyme fuel cell generated 68 μW (3.8 μW/cm 2 ) using glucose as the substrate, which was almost 9 times that of a single-module enzyme fuel cell. Thanks to the substrate specificity of bacterial FADGDH, cellulolytic sugars were revealed to be a good substrate for the enzyme fuel cell with cellobiose (9.3 μW/cm 2 ), cellotriose (9.2 μW/cm 2 ), or cellotetraose (6.3 μW/cm 2 ). These results demonstrated that together with the feasibility of using carbon cloth as the electrode material, FADGDH as the anode catalyst will become the norm in electrochemical biomass applications in the future.

“…The microfluidic enzymatic biofuel cells produced several orders of magnitude higher power densities than the microbial fuel cells ͑ϳ10 −3 mW cm −2 or higher͒. Zedba et al 27 achieved a power density of 0.11 mW cm −2 with a Y-shaped microfluidic fuel cell architecture, which is the highest power density reported in microfluidic biofuel cells to date. Further advancements would, however, be required for microfluidic biofuel cells to compete with nonbiological cells that are often capable of producing ϳ10-100 mW cm −2 .…”

“…The cathode was strategically placed upstream of the anode and, therefore, when the mixture of fuel and oxidant ͑air saturated glucose solution͒ was supplied, the consumption of O 2 at the upstream cathode protected the downstream anode from interfering O 2 molecules and consequently improved cell performance. An enzymatic biofuel cell using colaminar flow of glucose and O 2 in a Y-shaped microfluidic channel was developed by Zedba et al, 27 as illustrated in Fig. 7.…”

This review article presents how microfluidic technologies and biological materials are paired to assist in the development of low cost, green energy fuel cell systems. Miniaturized biological fuel cells, employing enzymes or microorganisms as biocatalysts in an environmentally benign configuration, can become an attractive candidate for small-scale power source applications such as biological sensors, implantable medical devices, and portable electronics. State-of-the-art biofuel cell technologies are reviewed with emphasis on microfabrication compatibility and microfluidic fuel cell designs. Integrated microfluidic biofuel cell prototypes are examined with comparisons of their performance achievements and fabrication methods. The technical challenges for further developments and the potential research opportunities for practical cell designs are discussed.

“…Based on this study, and by replacing carbon fibers by newly engineered porous microwires comprised of assembled and oriented carbon nanotubes, Mano's group (Gao et al, 2010) (Zebda et al, 2009a). Nowadays, these devices are capable of delivering 110 µW cm -2 for a cell voltage of 0.3 V (Zebda et al, 2009b) by using GOD and laccase as catalysts. Glucose/O 2 biofuel cells realized with classical fuel cell stacks have also been carried out (Habrioux et al, 2010).…”
