Abstract
A direct oxidation fuel cell (DOFC) having a liquid fuel and an anode electrode configured to generate power. The anode electrode includes a gas diffusion layer (GDL) and a microporous layer, such that a decrease in the porosity of the GDL achieves an increase in the power density of the DOFC.
