The invention relates to a fuel cell with integrated humidification, comprising a cathode-side or anode-side humidification unit with a heat exchanger, a condensate separator, a capillary tube and a Venturi nozzle and/or pump. The invention also relates to a method for humidifying process gas for the operation of a fuel cell wherein only product water is used and wherein, according to a first embodiment, the gas containing Ofor the cathode is humidified by the cathode off-gas which contains water vapor by means of a first humidification unit and/or the combustion gas containing Hfor the anode is humidified by the anode off-gas which contains water vapor by means of a second humidification unit or wherein, according to a second embodiment, the combustion gas containing Hfor the anode is humidified by the cathode off-gas which contains water vapor by means of a first humidification unit and/or the gas containing Ofor the cathode is humidified by the anode off-gas which contains water vapor by means of a second humidification unit.

Fuel cells are very well suited for the cogeneration of power and heat. An adaptation of the fuel cell power to the thermal requirement of the live load results in faulty adaptations and efficiency losses if the thermal requirement fluctuates significantly. The invention aims to achieve a continuous and lossless adaptation of the thermal production of the fuel cell to the current thermal requirement. The invention utilizes the fact that fuel cells are continuously adjustable over a broad load range. The invention proposes a continuous control of the current based on the supply or return temperature of the thermal circuit. According to the invention, a control method is used that has a quasi-continuous characteristic, particularly a control according to a PID-algorithm with additional limitation of the current as a control variable with respect to the minimum and the maximum value and of the amount of the time rate of change of the current. Such a control allows the fastest possible adaptation of the cell power to the respective thermal requirement.

Method for regulating operation of fuel cell installations controlled according to heat and/or power requirement

The invention relates to a device for combined purification and compression of hydrogen containing CO. Said device comprises a polymer electrolyte membrane (PEM) cell with a proton-conducting polymer membrane ( ), an anode on one side of the membrane and a cathode ( ) on the other side thereof. Said anode is in the form of a two-layer anode ( ) which comprises a CO-oxidation-selective catalytic layer ( ) on the side facing away from the membrane and an electrochemically active layer ( ) for oxidation of the hydrogen to form protons on the side facing the membrane. The PEM cell also has a flat, porous gas distribution layer provided on the anode side and attached to a current collector. Consequently, the PEM cell resists differential pressures of at least approximately 10 bar. The invention also relates to a process for combined purification and compression of hydrogen containing CO using said device. The CO in the hydrogen containing CO is oxidized selectively to form CO in the PEM cell, and the hydrogen subsequently extensively free of CO is compressed by the PEM cell by electrochemical means at differential pressures of at least approximately 10 bar. The resultant hydrogen is suitable as fuel in PEM fuel cells for vehicles.
