• Here we present a biofuel cell that can turn glucose and starch into electric energy. Compartmentalized with a Nafion<SUP>®</SUP> membrane, the cell oxidizes biofuels and reduces O<SUB>2</SUB> in the anolyte and catholyte, respectively. Glucose is oxidized by glucose oxidase (GOx), and the released electrons are transported to the anode by 1,4-benzoquinone (BZQ). Oxygen is reduced by laccase (Lac) that receives electrons from the cathode carried by 2,2'-azino-bis(3- ethylbenothiazoline-6-sulfonate) (ABTS). When starch is fed, amylase is added in the anolyte for saccharification. The cell can generate a power density of <I>ca.</I> 50 μW/cm<SUP>2</SUP> at 25°C rapidly, even with a starch fuel. In this paper, we will detail the factors that affect the cell performances and demonstrate the biofuel cell's niche in electronic devices.
