Abstract

We report the fabrication and characterisation of a non-compartmentalised, mediator and cofactor free glucose–oxygen biofuel cell based on adsorbed enzymes exhibiting direct bioelectrocatalysis, viz. cellobiose dehydrogenase from Dichomera saubinetii and laccase from Trametes hirsuta as the anodic and cathodic bioelements, respectively, with the following characteristics: an open-circuit voltage of 0.73 V; a maximum power density of 5 μW cm−2 at 0.5 V of the cell voltage and an estimated half-life of >38 h in air-saturated 0.1 M citrate–phosphate buffer, pH 4.5 containing 5 mM glucose.
