An Implantable Biofuel Cell for a Live Insect
A biofuel cell incorporating a bienzymatic trehalase|glucose
oxidase
trehalose anode and a bilirubin oxidase dioxygen cathode using Os
complexes grafted to a polymeric backbone as electron relays was designed
and constructed. The specific power densities of the biofuel cell
implanted in a female Blaberus discoidalis through incisions into its abdomen yielded maximum values of ca.
55 μW/cm<sup>2</sup> at 0.2 V that decreased by only ca. 5%
after ca. 2.5 h of operation
Bioelectrocatalytic Oxidation of Alkanes in a JP‑8 Enzymatic Biofuel Cell
Alkanes
are attractive fuels for fuel cells due to their high energy
density, but their use has not transitioned to biofuel cells. This
paper discusses the development of a novel enzyme cascade utilizing
alkane monooxygenase (AMO) and alcohol oxidase (AOx) to perform mediated
bioelectrocatalytic oxidation of hexane and octane. This was then
applied for the bioelectrocatalysis of the jet fuel JP-8, which was
tested directly in an enzymatic biofuel cell to evaluate performance.
The enzymatic catalysts were shown to be sulfur tolerant and produced
power densities up to 3 mW/cm<sup>2</sup> from native JP-8 without
desulfurization as opposed to traditional metal catalysts, which require
fuel preprocessing
