Abstract (en)
[origin: WO9960640A2] The invention relates to a PEM (polymer electrolyte membrane) fuel cell (BZ) with a novel humidification and cooling system. The inventive fuel cell consists of a membrane-electrode unit (ME) and at least one separator with structured channels. A liquid or a foam is added to the stream of fuel and/or the stream of oxidant for humidification and/or cooling.
