  • Patent number: 11120514
    Abstract: A domestic power plant has a housing which has an external air connection and an output air connection, and comprises a ventilation device with a heat exchanger. The ventilation device is connected to the external air connection such that external air can flow in a first air tract via the heat exchanger, or via an external air bypass past the heat exchanger, into a feed air tract of the domestic power plant. The feed air tract runs at least partially within the housing. The domestic power plant also has an exhaust air tract in which an air volume flow, brought about by the ventilation device, can be propagated within the housing and a fuel cell unit.
    Type: Grant

  • Patent number: 10886546
    Abstract: The invention relates to a flushing arrangement for flushing (purging) a fuel cell unit on its anode side and/or an electrolysis unit on its cathode side. The flushing arrangement has a flushing channel with a first and a second flushing channel section, which can be fluidically connected to one another via a purge valve of the flushing arrangement, and with a buffer store which is fluidically connected to the flushing channel and downstream of the purge valve, and which has a storage chamber that is provided for intermediate storage of a fluid mass to be flushed in a pulse-type manner with a flush mass flow from the fuel cell unit and/or from the electrolysis unit, so that this fluid mass can be discharged with a discharge mass flow, which is smaller than the flush mass flow, out of an outflow element fluidically connected to the second flushing channel section.

  • Patent number: 10855076
    Abstract: A method for operating a domestic energy generation installation comprises ascertaining or prespecifying at least one expectation time period, ascertaining an expected load profile of an electrical consumer, ascertaining an expected yield profile of the regenerative energy source in the expectation time period, ascertaining or prespecifying a minimum consumption power which should be available for withdrawal from the storage battery unit, ascertaining an energy balance over one expectation time period from the expected yield profile and the expected load profile, ascertaining a time range of the storage battery unit from the expected load profile, the expected yield profile and the minimum consumption power, which should not be undershot at any time, and from a currently ascertained state of charge of the storage battery unit, operating the fuel cell unit depending on the ascertained time range and operating the electrolysis unit depending on the ascertained energy balance.
