  • Publication number: 20250179670
    Abstract: The invention relates to a method for operating an electrolyzer (10) for the production of hydrogen and oxygen, comprising a membrane (22), which is permeable to OH ions and separates an anode chamber (14) from a cathode chamber (16), said method comprising at least the following method steps: a) temporary dry operation of the cathode chamber (16), b) temporary diffusion of water molecules through the membrane (22) from the anode chamber (14) into the cathode chamber (16), c) variation of a differential pressure (42) between the cathode chamber (16) and the anode chamber (14) by means of a restrictor valve (46), and d) adjustment of the moistening/wetting of the cathode chamber (16) by adjusting a defined differential pressure (42).

  • Publication number: 20220316074
    Abstract: A method for electrochemical hydrogen compression. The method includes: providing hydrogen gas having a relative humidity RH of 100%; providing inert gas having a relative humidity RH of 100%; mixing the humidified hydrogen gas and the humidified inert gas; electrochemically oxidizing the hydrogen gas at an anode; transporting the protons obtained as a result of the oxidation and at least a portion of the humidified inert gas through a membrane; and electrochemically reducing the protons at a cathode into hydrogen.

  • Patent number: 9588093
    Abstract: A device for determination of the H2 content of H2/natural gas mixtures comprises an input interface configured to read in a calorific value of a first H2/natural gas mixture from a delivery station of a gas grid, an input interface configured to introduce a second H2/natural gas mixture into the device; a proton-conducting layer fluidically connected to the input interface of the second H2/natural gas mixture and configured to permit determination of a current-voltage characteristic, a volumetric flow rate sensor configured to determine a volumetric flow rate of the second H2/natural gas mixture into the proton-conducting layer, and a control apparatus connected to the proton-conducting layer, the input interface of the second H2/natural gas mixture, and the volumetric flow sensor. The control apparatus is configured to determine whether there is a hydrogen depletion of the proton-conducting layer, and output the current calorific value of the second H2/natural gas mixture.

  • Publication number: 20160372775
    Abstract: The disclosure relates to a method for temporarily storing the electric energy of an energy supply system. The method comprises the steps: receiving the electric energy via an interface to the energy supply system; carrying out electrolysis in order to convert the electric energy into chemical reaction energy and an oxidant; and storing the chemical reaction energy in a fluid reservoir.

  • Publication number: 20150144501
    Abstract: A method for conditioning hydrogen includes positioning hydrogen on a suction side of an electrochemical compressor. The hydrogen includes at most a fractional amount of an extraneous species. The electrochemical compressor includes a first electrode on a suction side and a second electrode on a pressure side and is configured to apply an electrical potential between the first and second electrodes. The method further includes transporting ions of the hydrogen through a membrane of the electrochemical compressor via the electrical potential in order to increase a hydrogen partial pressure on the pressure side of the electrochemical compressor and such that the extraneous species remains on the suction side of the electrochemical compressor.

  • Patent number: 6539730
    Abstract: A method and a device for use in the air conditioning of an interior of a motor vehicle equipped with an air conditioning system. In particular, the condensation water, produced when operating the air conditioning system while driving, is collected when the vehicle is standing still, and the intake air supplied to the interior or the outgoing air removed from the interior is humidified with the collected water so that the vehicle is cooled by evaporative cooling when it is standing still. While driving, the outside air intake may be pre-cooled by the cooled outgoing air by using a heat exchanger.
