A Novel, Small High-power Output Biofuel Cell

The development of small, high-power output biofuel cells as alternate power sources are very important for stand-alone sensors, sight and illumination devices, implantable devices, and biological sensors. The biofuel cells must be lightweight, cost-effective, and provide greater power densities than currently available power sources. This Phase I SBIR proposal describes the development of a dual enzyme-based biofuel cell that contains a specially formulated polymer for each electrode. The polymers will enhance the stability of the enzymes, improve their immobilization on the substrates (electrode), increase the electron transfer rate between electrodes and boost the power output of the biofuel cell.
