Abstract

A direct electron transfer biofuel cell consisting of a pair of single walled carbon nanotubes and enzymes on a single plane is reported, which allows for extremely close spacing of electrodes. The discrete device has a measured power and current density of 18 mW/cm² and 90 mA/cm², respectively, into 200 TΩ. Analysis of measurements from up to 3 million devices in parallel shows that the performance will improve by at least 2 orders of magnitude at peak power.
