“…NQ is low-cost and has no observable adverse impact to the environment. The combination of NQ and AC composite as anode catalyst for glucose oxidation has better performance than those previously reported [27,29,30]. We believe this work can be a starting point to construct high-performance, cheap, and environmentally friendly DGAFCs.…”

Abstract:Six different electron mediators were immobilized on the activated carbon (AC) anode and their effects on performance of a direct glucose alkaline fuel cell were explored. 2-hydroxy-1, 4-naphthoquinone (NQ), methyl viologen (MV), neutral red (NR), methylene blue (MB), 1, 5-dichloroanthraquinone (DA) and anthraquinone (AQ) were doped in activated carbon (AC), respectively, and pressed on nickel foam to fabricate the anodes. NQ shows comparable performance with MV, but with much lower cost and environmental impact. With NQ-AC anode, the fuel cell attained a peak power density of 16.10 Wm´2, peak current density of 48.09 Am´2, and open circuit voltage of 0.76 V under the condition of 1 M glucose, 3 M KOH, and ambient temperature. Polarization curve, EIS and Tafel measurements were also conducted to explore the mechanism of performance enhancement. The high performance is likely due to the enhanced charge transfer and more reactive sites provided on the anode.

Low cost electric power generation using raw juice from culled papaya or fruit waste as feedstock was achieved in a sugar-air alkaline battery (SAAB) with about 37% coulombic efficiency at 0.7-0.8 mW cm -2 near peak power density. Such fruit waste, juice-based electrochemical energy could be poised as sustainable distributed energy resource for remote or underdeveloped regions that need cheap electricity without complicated infrastructure. © The Author(s) 2016.

Published May 11, 2016 More than one billion people still have no access to electricity, as conventional grid-connected utility is either unavailable or cost prohibitive in many remote or underdeveloped areas globally.1 In these areas, it is extremely challenging to develop a feasible solution to provide electricity, since the energy feedstock has to be easy to obtain, store and distribute locally. Also, the system has to be easy to operate and maintain without training, advanced skill set, and infrastructure.Abiotic reducing sugar-air alkaline battery (SAAB) or fuel cell (SAFC) systems ( Figure 1) recently have been shown capable of harnessing electric power from partial oxidation of various reducing sugars using strong base solutions and mediator dyes.2-6 The reaction mechanism of SAAB is discussed in detail by Scott et al. 4 The SAAB uses inexpensive electrode materials in concentrated potassium or sodium hydroxide solution, in one compartment 2,4,5 without using expensive separators (e.g. Nafion) or (bio-)catalysts. Methyl viologen (MV) and indigo carmine (IC) are among the best mediators for charge transfer. 5For practical use, cheap feedstock is essential. A significant quantity of unmarketable culled papaya and processing waste are available in Hawaii and many other regions around the globe, especially in developing economies. Instead of subjecting the fruit waste to microbial fermentation to make biogas, ethanol, or lipids as biofuels, they can serve as cheap feedstock for SAAB to generate electricity. Microbial fermentation of papaya fruit wastes for biofuels or bioenergy requires substantial infrastructure and water-and energy-demanding processing. Furthermore, fermentation is sensitive to environmental factors (e.g. temperature and humidity) and impurities (e.g. inhibitors in fruit wastes could impair ethanol or lipid production). The SAAB, in contrast, is very forgiving in the quality of sugar feedstock, and hence the cost (i.e. $ kg -1 for feedstock and $ kWh -1 for electricity) and complexity of the energy harvesting process could be drastically reduced. Papaya has high content of glucose and fructose, 7 and polysaccharides that cou...
