摘要：

A glucose-O2 biofuel cell, consisting only of two electrocatalyst coated 7-μm diameter, 2-cm long carbon fibers is reported. The cell operated continuously at 0.52 V at 37 °C in a physiological buffer solution for a week, producing 1.9 μW during the first and 1.0 μW during the last day, generating in the period 0.9 J of electrical energy while passing a charge of 1.7 C. If a similar dimension zinc fiber were utilized in a battery at 100% current efficiency, only 0.016 C would have been generated. Copyright © 2002 American Chemical Society.
