Abstract (en)

[origin: WO0123874A1] The invention relates to a method for determining alcohol concentrations in an alcohol/water-mixture found in fuels cells operated using said mixture, in particular direct-methanol-fuel-cells. A portion of the alcohol/water-mixture is separated and transported against a predefined pressure. The separated part of the mixture is heated to boiling, the boiling temperature is measured and the amount of alcohol in the mixture is determined.
