Abstract

Here, we demonstrate the use of phospholipid micelles to enhance O₂ concentrations by two-fold at the surface of a bilirubin oxidase biocathode. Specifically, 1,2-diarachidoyl-sn-glycero-3-phosphocholine was used in a glucose enzymatic fuel cell to limit power losses due to O₂ transport, even in a quiescent solution.
