Abstract
The invention relates to a DMFC in which an evaporation apparatus is connected before the cell. The fuel, which is predominantly a methanol/water mixture with a possible admixture of inert gas, is variable in its composition, whereby the respective methanol/water and, if warranted, inert gas mixture, can be adjusted in load-dependent fashion. Moreover, the invention relates to a method for operating a DMFC apparatus in which the fuel is present in the anode chamber in gaseous form.
