An evaporator stack, in particular for a double evaporator, includes foils for converting a liquid medium into a gaseous medium. The foil stack has at least one foil through which a medium flows and at least one additional foil. The foil stack has an inlet region for the liquid medium and a discharge region for the gaseous medium. The discharge region is designed such that a pressure gradient in the medium over the at least approximately entire width of the discharge region is smaller than a pressure gradient in the medium over the at least approximately entire length of the media foil through which flow occurs.
