Abstract

A device for evaporating liquids includes a porous, thermally conductive evaporation body, which contains a catalyst material on one surface, while the evaporation body is gas-impermeable on the opposite surface. Liquid which is to be evaporated and, if appropriate an additional fuel, can be fed to the evaporation body. The heat of evaporation required is provided by an exothermic reaction of the liquid or with a gaseous oxidizing agent at the catalyst material.
