摘要：

A glassy carbon electrode modified with bilirubin oxidase (BOD) cross-linked to an Os redox polymer functions as a bio-cathode for a 4-electron reduction of O-2 under neutral conditions. On the other hand, a glassy carbon electrode modified with pyrroloquinoline quinone-dependent soluble glucose dehydrogenase (sGDH) or glucose oxidase crosslinked to an Os redox polymer functions as a bio-anode for a 2-electron oxidation of glucose. A prototype of a one-compartment glucose/O-2 biofuel cell without a separator was constructed by using the BOD-modified cathode and the sGDH-modified anode. The maximum power density was 0.058 mW cm(-2). The loss in the power is discussed in terms of thermodynamics and kinetics.
