Abstract
A direct alcohol fuel cell having a proton exchange membrane (PEM) separating an anode section from a cathode section, which cathode section contains a cathode collection element electrically connected to a cathode catalyst, the cathode catalyst being in diffusive communication with a gaseous oxidant, and which anode section comprises an anode collection element electrically connected to an anode catalyst. The anode catalyst is in diffusive communication with a fuel supply. The PEM is structured to have a bottom and walls extending from the bottom to a containment distance into the cathode section, and the cathode catalyst is located within the containment distance from the bottom. The fuel cell is suited for a microelectronic device.
