“…Many challenges persist for the wide spread use of enzymatic fuel cell technology that have appeared as one of the ecofriendly energy‐production technology from naturally accessible fuels (sugars, etc.). Current density and long‐term stability are important issues that needs to be solved before commercial applications . The other important problem for the enzymatic biofuel cell applications is membrane development.…”

Considerably stable enzymatic fuel‐cells (single cell and 5‐cells stack) were prepared by using chitosan based membranes along with glucose oxidase attached bioanode. Continuous operation of fuel‐cells were monitored under short circuit conditions reaching half‐life over a week. Detailed analysis for the effects of pH, temperature, buffer types and concentration on different type of in‐house produced chitosan membranes were performed by electrochemical impedance spectroscopy (EIS). EIS was utilized to observe, total electrolyte resistance, charge transfer properties, mass transfer and double layer effects on integrated fuel cells (single cell and 5‐cells stack). Performance of the fuel cells was also analyzed by the polarization experiments. Current density of the fuel cell increased at higher operation temperatures not only due to better enzyme kinetics, but also due to increase in electrolyte (membrane+buffer solution) conductivity. Buffer concentration in the fuel (glucose) solution was found as an important parameter. Under optimum fuel cell operation conditions (i. e. 30–40 °C, pH 5 0.3 M buffer solution), maximum current densities of 3.0–3.2 mA cm−2 were reached. Low‐power devices (i. e. a calculator, step motor) were powered with 5‐cell stack producing 3 mW at 1.3 V.

“…EBFCs convert biofuel into electrical energy, by utilizing the chemical energy of the biochemical pathways catalyzed by enzymes such as electro‐catalysts, instead of metal catalysts . EBFCs have been used in implantable devices in the healthcare industry for powering devices like pacemakers, and laccase‐based EBFCs have been even proposed as wearable electronic devices such as smart watches, fitness bands and wearable electrocardiogram (ECG) detectors …”

The application of enzymes offers an enormous potential in the improvement of existing industrial procedures and in the establishment of new processes for obtaining high-added value products. Enzymes provide cleaner and more efficient industrial processes and contribute to the sustainability concept. In this sense, laccases are very versatile biocatalysts currently used in food, textile and pulp and paper sectors among others. During the last years, scientific efforts have been diverted to the exploitation of such interesting enzymes in novel fields like lignocellulosic biorefineries, biosensors or enzymatic biofuel cells. This review provides a general vision of the use of laccase enzymes describing their main characteristics and mode of action. Furthermore, their current uses in industrial processes are summarized and the most novel potential application of laccases are revealed. The increasing interest on laccases is also demonstrated by the research efforts on enzyme engineering as it is detailed in this review. wileyonlinelibrary.com/jctb www.soci.org AD Moreno et al.

“…Glucose-based EBFC seems to be a promising candidate for implantable applications, due to the availability of glucose and oxygen in physiological fluids that make the possibility for the generation of electrical power inside the living system. The glucose used as a fuel oxidizes at the anode via redox enzyme, whereas the reduction of oxygen takes place at the cathode, to carry out redox reaction [12]. To date, various redox enzymes have been exploited, such as glucose dehydrogenase [13], fructose dehydrogenase [4], cellobiose dehydrogenase [14], and glucose oxidase (GOx) [3], as biocatalysts for the anode modification.…”

In this work, nano-inspired nickel oxide nanoparticles (NiO) and polythiophene (Pth) modified bioanode was prepared for biofuel cell applications. The chemically prepared nickel oxide nanoparticles and its composite with polythiophene were characterized for elemental composition and microscopic characterization while using scanning electron microscopy. The electrochemical characterizations of polythiophene@NiO composite, biocompatible mediator ferritin (Frt) and glucose oxidase (GOx) catalyst modified glassy carbon (GC) electrode were carried out using cyclic voltammetry (CV), linear sweep voltammetry (LSV), and charge-discharge studies. The current density of Pth@NiO/Frt/GOx bioanode was found to be 5.4 mA/cm2. The bioanode exhibited a good bio-electrocatalytic activity towards the oxidation of the glucose. The experimental studies of the bioanode are justifying its employment in biofuel cells. This will cater a platform for the generation of sustainable energy for low temperature devices.
