Abstract

The invention relates to a method for operating a direct methanol fuel cell. A cooling agent is vaporized in the fuel cell, and a methanol-water mixture is vaporized in a vaporizer, using excess heat from the fuel cell. The vaporized mixture is then conveyed to the anode chamber of the fuel cell.
