Abstract
Glucose biofuel cells (GBFCs) are highly promising power sources for implantable biomedical and consumer electronics because they provide a high energy density and safety. However, it remains a great challenge to combine their high power density with reliable long-term stability. In this study, a novel GBFC design based on the enzyme biocatalysts glucose dehydrogenase, diaphorase, and bilirubin oxidase immobilized in rolled-up titanium nanomembranes is reported. The setup delivers a maximum areal power density of ≈3.7 mW cm−2 and a stable power output of ≈0.8 mW cm−2. The power discharges over 452 h, which is considerably longer than reported previously. These results demonstrate that the GBFC design is in principle a feasible and effective approach to solve the long-term discharge challenge for implantable biomedical device applications.
