Abstract: The present invention relates to a direct alcohol fuel cell comprising a housing containing a proton exchange membrane (PEM) separating an anode section from a cathode section, which anode section and which cathode section are contained in the housing, the cathode section comprising a cathode collection element having one or more ventilation holes, which cathode collection element is electrically connected to a cathode catalyst, which cathode catalyst is in diffusive communication with a gaseous oxidant, and the anode section comprising an anode collection element electrically connected to an anode catalyst, the DAFC comprising an oleophobic filter covering the ventilation hole(s). The oleophobic filter may be held in place using any appropriate means as desired. The fuel cell is suited for a microelectronic device.
