Multiwalled carbon nanotubes to improve ethanol/air biofuel cells

- The architecture of bioanodes layers makes a great difference in the wiring between de CNTs and the ADH enzyme.
- MWCNTs enhance the activity of the enzymatic reaction between EtOH and the NAD+.
- The anode configuration carbon cloth/poly-MG/PAMAM/MWCNTs/ADH is potentially applicable in miniaturized energy devices.
- Power density and open circuit potential (OCP) of 0.278 ± 0.038 mW cm−2 and 0.459 ± 0.025 V were obtained for the best anode configuration investigated.
