“…The occurrence of hydrogen ions in the anode diffusion layer evidences also a backward diffusive flux, caused by the presence of a potential across the cell. The peak concentration of hydrogen ions is observed roughly near the enzyme layer at steady state, since migration and cathode kinetics become dominant factors, reducing the effect of diffusion phenomena and generation of hydrogen ions in the enzyme layer [52]. Figure 17b shows the variation of hydrogen ions across the enzymatic cell as a function of temperature: Higher operating temperature results in higher concentration of hydrogen ions in the enzyme layer, depending on the enhanced diffusive flux and reaction rate, as in the case of glucose concentration variation along the cell.…”

Because of environmental concerns, there is a growing interest in new ways to produce green energy. Among the several studied applications, enzymatic biofuel cells can be considered as a promising solution to generate electricity from biological catalytic reactions. Indeed, enzymes show very good results as biocatalysts thanks to their excellent intrinsic properties, such as specificity toward substrate, high catalytic activity with low overvoltage for substrate conversion, mild operating conditions like ambient temperature and near-neutral pH. Furthermore, enzymes present low cost, renewability and biodegradability. The wide range of applications moves from miniaturized portable electronic equipment and sensors to integrated lab-on-chip power supplies, advanced in vivo diagnostic medical devices to wearable devices. Nevertheless, enzymatic biofuel cells show great concerns in terms of long-term stability and high power output nowadays, highlighting that this particular technology is still at early stage of development. The main aim of this review concerns the performance assessment of enzymatic biofuel cells based on flow designs, considered to be of great interest for powering biosensors and wearable devices. Different enzymatic flow cell designs are presented and analyzed highlighting the achieved performances in terms of power output and long-term stability and emphasizing new promising fabrication methods both for electrodes and cells.

“…Among renewable energy sources, direct glucose fuel cells (DGFCs) have been examined most extensively due to their intrinsic high efficiency, environment-friendly and silent operation, good stability, considerable durability and sim-ple structure. Great efforts have been devoted to the investigation of glucose application as a fuel over the past decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Glucose is an ideal renewable fuel since it is easily available, cheap and abundant in nature, non-flammable, odourless, non-toxic, environmentally benign and safe, easy to produce and handle.…”

The electrochemical oxidation of glucose was investigated on the Co and CoB alloy coatings, which were deposited on the copper substrate (Cu) and subsequently modified with a small amount of Au nanocrystallites. The catalysts were prepared via a simple electroless Co deposition method followed by a spontaneous Au galvanic displacement from the Au(III)-containing solution. The activity of Co and CoB alloy coatings modified with Au crystallites towards the oxidation of glucose was examined by the cyclic voltammetry method.It has been determined that the Co and CoB alloy coatings, which were modified with a small amount of Au crystallites, exhibit a significantly higher activity for the oxidation of glucose as compared to that of bare Au, Co and CoB alloy catalysts. The process of glucose oxidation is significantly shifted to a more negative potential domain at the both Co/Cu and CoB/Cu catalysts modified by Au nanocrystallites, indicating the higher activity of those catalysts as compared to that of the unmodified Co/Cu and CoB/Cu catalysts and the bare Au electrode. It was found that ca. 22 and even 67 times higher glucose oxidation current density values have been obtained at the AuCo/Cu and AuCoB/Cu catalysts, respectively, as compared to those for the unmodified CoB/ Cu and Co/Cu.
