  • Water atomization apparatus for a fuel cell system and also a method for humidifying a gas flow supplied to a fuel cell system
    Patent number: 7651796
    Abstract: A water atomization apparatus for a fuel cell system, comprising a plurality of fuel cells connected together to form a fuel cell stack and each having an anode, a cathode and a membrane, with the fuel cell stack having an anode side with an inlet for a fuel and an outlet for non-consumed fuel and exhaust gases which arise at the anode side, a cathode side with an inlet for a gaseous oxidation agent such as air and an outlet for exhaust gases arising at the cathode side, and a compressor connected upstream of the cathode side inlet, is characterized in that the water atomizing apparatus comprises a supply tank for deionized water, a pressure pump which is connected to the supply tank, a reservoir which is fed by the pressure pump and contains deionized water under pressure in operation, a pressure regulating valve having an inlet connected to the reservoir and determining the operating pressure which prevails in the reservoir and also at least one controllable injection valve which injects atomized water into
