1. A direct alcohol fuel cell (DAFC) comprising:
an anode terminal electrically connected to an anode catalyst in fluid communication with a fuel supply,
a cathode catalyst in fluid communication with a gaseous oxidant, an electrically conducting cathode plate having a collecting element with evaporation holes, a bendable segment and a terminal site, which collecting element is electrically connected to the cathode catalyst, and
a housing containing the collecting element, and a proton exchange membrane (PEM) between the anode catalyst and the cathode catalyst,
wherein the collecting element comprises at least one guidance hole on an edge of the collecting element, the at least one guidance hole being positioned on at least one side of the bendable segment at a point where the bendable segment joins the edge of the collecting element.
