BASISELEMENT VON BRENNSTOFFZELLE ZUR REDUCIERUNG DES DURCHGANGES VON METHANOL DURCH ELEKTROLYT

摘要

A basic element for a proton exchange membrane (PEM) fuel cell, especially a direct methanol fuel cell, comprises an electrolyte (23) between an anode and a cathode (20). The anode comprises an internal part (32) buried in the electrolyte and electrically connected to an external part (31) contacting the electrolyte on one side. Preferred Features: The electrolyte (23) is in the form of a film or a layer. The internal part (32) of the anode is substantially parallel to the external part (31) of the anode, and comprises at least one grid, at least one foam material, or a number of layers of different materials. The fuel is an alcohol selected from ethanol, methanol and ethylene glycol.
