摘要： 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.

摘要： The invention relates, inter alia, to a purging system, which is provided for purging at least one energy source device and/or at least one energy sink device of an energy system, comprising a purging device, which is provided in such a way that the purging device is able to produce a discharge volumetric flow (42) containing hydrogen during a purging process. The aim of the invention is to further advantageously modify a purging system of the type in question in order to avoid explosion hazards due to hydrogen in the discharge volumetric flow after a purging process, by means of economical measures of simple design. This aim is achieved, according to the invention, in that the purging system has a mixing device (44) downstream of the purging device in the flow direction of the discharge volumetric flow (42), which mixing device is provided for mixing the discharge volumetric flow (42) with an air volumetric flow (28), in particular an exhaust air volumetric flow, and that the mixing device (44) has a wall (47), which delimits a defined open thorough-mixing space (45) for the mixing of the discharge volumetric flow (42) with the air volumetric flow (28), the wall (47) delimiting only a subregion of the thorough-mixing space (45), and the region of the mixing device (44) not delimited by the wall (47) forming an entry region (48) for the two volumetric flows.

摘要： The present invention relates, inter alia, to a method for storing a medium, in particular a gas, in a pressure storage device (31), wherein, in a preferred embodiment, a dynamic operating pressure, which is dependent on measured temperature values and up to which the medium can be stored in the pressure storage device (31), is determined. In particular, the invention allows dynamic storing of medium in the pressure storage device (31) in respect of the storage pressure, in particular the operating pressure, with a simple design. This is achieved by the dynamic operating pressure being determined, in particular calculated, on the basis of dynamic reference temperature values as a function of time. The method is preferably carried out in an energy system (10), having at least one energy source device (21) for generating a medium and a pressure storage device (31), spatially separated therefrom, for storing the generated medium.

摘要： 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.
