Methanol fuel cell comprises anion conducting membrane arranged between anode chamber and cathode chamber, and means for feeding water from anode chamber to cathode chamber
A methanol fuel cell comprises an anion conducting membrane arranged between an anode chamber and a cathode chamber; and means for feeding water from the anode chamber to the cathode chamber. Independent claims are also included for the following: (A) a fuel cell stack consisting of two of the above methanol fuel cells and at least one methanol fuel cell having an acidic electrolyte as means for removing methanol; and (B) a process for operating a methanol fuel cell comprising allowing hydroxyl ions to flow from the cathode side to the anode side through the membrane; feeding a methanol/water mixture from the anode chamber to a further fuel cell; and feeding water from the cathode chamber of the further cell to the cathode chamber of the previous cell.
