  • Patent number: 11302939
    Abstract: A direct liquid fuel cell power generation device comprises a direct liquid fuel cell system and a low-temperature auxiliary starting component. A heat exchanger is arranged at a stack cathode inlet. The heat of a fuel solution at a stack anode outlet is used to heat the air. The heat generated by an electronic load for starting is used to heat a condenser. The heat of a methanol solution at a liquid outlet of a gas-liquid separator is used to preheat high-concentration fuel flowing into a refueling pump. Starting and operation in a low-temperature environment can be realized through auxiliary heating of external power supplies such as the low-temperature auxiliary starting component or an in-vehicle cigarette lighter. Organic micromolecule substances such as methanol and ethanol are used as fuel and are subjected to catalytic combustion in a catalytic combustor.

  • Patent number: 11121416
    Abstract: An adsorption assembly and a battery are provided. The adsorption assembly includes: a housing including a gas permeable portion; and an adsorbent encapsulated by the housing. The adsorption assembly can effectively isolate the adsorbent from the external environment by providing the housing, thereby preventing the adsorption performance of the adsorbent from being affected, and the housing includes a gas permeable portion, which can make the produced gas in the external environment enter the housing and be effectively adsorbed by the adsorbent. In particular, when the adsorbent is used for a battery, especially a soft pack battery, the gas produced inside the battery can be effectively adsorbed to prevent liquid leakage of the battery seal caused by breakage of the battery seal by gas, improving reliability and safety of the battery and extending lifetime of the battery.

  • Patent number: 11111140
    Abstract: The invention provides an apparatus for generating hydrogen including first and second reactant containers linked to a reactor vessel. The reactant containers contain reactants which, when mixed in the reactor vessel, react to form hydrogen gas. Peristaltic pumps pump the reactants from the reactant containers to the reactor vessel. The peristaltic pumps are selected to provide a maximum pumping pressure in the range from 0.1 bar to 10 bar. An electronic control means is programmed to control the flow of reactants to the reactor vessel so as to maintain the pressure of hydrogen gas within the apparatus at a value of no more than 10 Bar.

  • Patent number: 10847817
    Abstract: The invention relates to a method to determine a content of a gas component in a gas mixture delivered recirculating through an anode chamber (12) or a cathode chamber (13) of a fuel cell (10), wherein the delivery takes place via a delivery device (26) functioning according to the positive displacement principle. The invention also relates to a fuel cell system (100) configured to execute the method. According to the invention, the content of the gas component is determined depending on geometric parameters (V, ?) and operating parameters (n, U, I) of the delivery device (26), as well as on thermodynamic state variables (p, T) of the gas mixture. The sought target quantity, for example a hydrogen component of an anode gas, can thus be determined in a simple and robust manner from quantities that are already known or measured.
