  • Publication number: 20240384421
    Abstract: The present invention relates to a steam electrolysis system for the production of hydrogen. The system comprises at least one steam electrolyser cell, at least one feeding gas arrangement comprising at least one electric steam generator, at least one feeding gas supply route for supplying a flow of feeding gas comprising at least steam from the at least one feeding gas arrangement to the at least one steam electrolyser cell, at least one gas moving device for removing hydrogen from the at least one steam electrolyser cell, and at least one external power supply source for operating the system. The at least one external power supply is electrically coupled to the at least one electric steam generator of the feeding gas arrangement and to the least one steam electrolyser cell. The at least one steam electrolyser cell and the at least one electric steam generator are electrically connected in parallel.

  • Publication number: 20190393525
    Abstract: A combined hydrogen and electricity supply system for producing hydrogen, electrical Power (P) and co-production, the system including a variable electrical load for varying the amount of impedance on the system, a pre-reformer connected to a stream of carbonaceous fuel, a stream of steam and connected to a heating source. The pre-reformer produces a first reformate gas having at least hydrogen, carbon monoxide and unconverted carbonaceous fuel. The pre-reformer is responsive to the amount of heat provided by the heating source, a solid oxide fuel cell stack coupled to the variable electrical load and coupled to the first reformate gas. The ratio between electrical power (P) and amount of hydrogen produced depends at least on the variable electrical load and the heat provided by the heating source.

  • Patent number: 10297849
    Abstract: Method and system for producing CO2, purified hydrogen and electricity from a reformed process gas feed using a solid oxide fuel cell. The method having the steps of: introducing the reformed process gas into the solid oxide fuel cell; converting hydrogen and CO of the reformed process gas in combination with oxygen into an anode off-gas including steam, CO2 and unconverted process gas; introducing the anode off-gas into a high temperature water gas shift reactor; in the high temperature water-gas shift reactor, converting CO and steam into CO2 and hydrogen, introducing the gas exiting the high temperature water-gas shift reactor into a low temperature water-gas shift membrane reactor, in the low temperature water-gas shift membrane reactor, converting CO and steam into CO2 and hydrogen, whereby the low temperature water-gas shift membrane reactor comprises a hydrogen pump producing purified hydrogen on a permeate side, while removing hydrogen from a feed side.

  • Patent number: 8172196
    Abstract: A device for supporting a mobile calorimeter on a measuring object, especially a monitor, includes a flexible tube-shaped carrying belt (G) which is at least partially filled with a granular loading material and which is provided with a fixing member (1) for its installation on the calorimeter (MD). The supporting device may further include a pocket (T) provided with measuring and operating apertures for receiving the mobile calorimeter (MD), and the carrying belt (G) may be fastened to the pocket (T). The carrying belt (G) may be formed substantially as a closed loop and may be provided with a Velcro fastener for its lengthwise adjustment. The supporting device permits easy and comfortable positioning of the measuring apparatus on a monitor and at the same time serves as a carrying belt.
