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.
