“…5 The power densities obtained are eight times higher compared to the highest power density obtained in bio-fuel cells reported. 29 Results of this study are comparable with those from a previous study where lter paper was used as the substrate. 5 An advantage of the current cell is the biocompatibility of the device which makes it desirable as a bio-fuel cell.…”

In this paper, polyvinylidene fluoride (PVDF) nanofibers have been suggested as a viable substrate for flexible and implantable electrochemical devices. PVDF electrospun nanofibers exhibit excellent mechanical properties, flexibility, chemical stability, and biocompatibility, making them a potential option in the development of implant fuel cells. This paper presents a membraneless hydrogen peroxide fuel cell that is fabricated to demonstrate the possibility of using these nanofibers as the substrate for electrochemicaldevices. An open circuit potential of 0.65 V was achieved for the cell fabricated using Prussian Blue (PB) as the cathode material and nickel and aluminium as the anode materials. The power produced by the cell was $1 mW cm À2 at 0.32 V. The results presented compare favourably with available power generators reviewed in the literature. Based on the proof of concept demonstration; PVDF electrospun nanofibers can be successfully used for implantable electrochemical devices such as bio-fuel cells and self-sustained point-of-care diagnostic systems.

“…For example, nanostructured carbons, such as carbon nanotubes [3][4][5][6][7] and carbon blacks, [8][9][10] and mesoporous carbons, such as carbon cryogel [11][12][13][14][15] and carbon aerogel, 16,17 have been investigated for use as enzyme electrode scaffolds. Carbon nanotubes and carbon blacks aggregate and create mesospaces suitable for enzymatic reactions.…”

MgO-templated porous carbon (MgOC) was developed for D-fructose dehydrogenase (FDH) electrodes. MgOCs with an average pore diameter ranging from 10 to 100 nm were used in this study. FDH adsorbed on a MgOC electrode exhibited significant catalytic currents for D-fructose-oxidation without a redox mediator. When the pore size of MgOC was much larger than the size of FDH, a sufficient amount of FDH was adsorbed in the mesopore on and even inside the MgOC structure. In contrast, when the pore size of MgOC was comparable to the size of FDH, the catalytic current depended only on the amount of enzyme adsorbed in mesopores formed at the surface of the carbon particles; however, an enhanced thermal stability of FDH was observed. Thus, FDH was stabilized through encaging in carbon mesopores with a size comparable to that of the enzyme.

A porous carbon electrode with a branch structure composed of macropores and mesopores was prepared using MgO-templated carbon and MgO particles by screen-printing. The electrode characteristics were investigated using electrochemical impedance spectroscopy. Loci of the straight line with angles at 22.5°and 45°were observed in the high-and mid-frequency ranges, respectively. A partial semicircle appeared in the low-frequency range. The impedance analysis revealed that almost the entire charge-transfer reaction occurred only at the mesopore interface of the electrode. The current density of the bilirubin oxidase (BOD)-immobilized branch structure carbon electrode was 1.3 times higher than that of the BOD-immobilized non-branch structure carbon electrode.

Flexible and high-performance paper-based biofuel cells using printed porous carbon electrodes

Abstract: We demonstrate a flexible paper-based biofuel cell using porous carbon inks for high power output. The power density of the fabricated biofuel cell reached 0.12 mW cm(-2) (at 0.4 V), which is the highest output power reported to date, to the best of our knowledge.
