Abstract (en)

[origin: DE19741331A1] The invention relates to a device with a fuel cell and cooling means in addition to a cooling method in order to operate such a device. The fuel cell is cooled by converting a liquid into a gas. The heat which is to be dissipated is therefore supplied to a liquid which is thus converted into a gas. The liquid is heated to a boiling temperature before entering the fuel cell. The boiling temperature is lower than the operating temperature of the fuel cell. As a result, a homogeneous temperature distribution in the fuel cell is achieved.
