METHOD AND DEVICE FOR OPERATING A DIRECT METHANOL FUEL CELL WITH GASEOUS FUEL

摘要

The invention relates to a method for operating a direct methanol fuel cell. A cooling agent is vaporised in the fuel cell and a methanol-water mixture is vaporised in a vaporiser (V1). Excess heat from the fuel cell is used for vaporising the methanol-water mixture. Said vaporised methanol-water mixture is then conveyed to the anode chamber of the fuel cell. The invention also relates to a device with a direct methanol fuel cell. A cooling agent line is located in the direct methanol fuel cell and a vaporiser is provided. A fuel supply line delivers fuel to the vaporiser. Fuel which has vaporised in the vaporiser is then conveyed into the anode chamber of the fuel cell by a line. Elements are provided for transferring the excess heat from the fuel cell to the vaporiser.
