    • The invention relates to a domestic power plant (500), in particular for self-sufficient energy provision of a residential building with electricity and/or heat. The domestic power plant has a housing (550) which has an external air connection (16) and an output air connection (24), and comprises a ventilation device (12) with a heat exchanger (34). The ventilation device (12) is connected to the external air connection (16) such that external air (AUL) can flow in a first air tract (14) via the heat exchanger (34), or via an external air bypass (14') past the heat exchanger (34), into a feed air tract (15) of the domestic power plant (500). The feed air tract (15) runs at least partially within the housing (550). The domestic power plant also has an exhaust air tract (30) in which an air volume flow, brought about by the ventilation device (12), can be propagated within the housing (50). In addition, the domestic power plant has a fuel cell unit (200) which is preferably arranged within the housing (550) and is integrated into the exhaust air tract (30) such that undesired gas released in the fuel cell unit (200) is diluted by the air volume flow and can be removed together with waste heat from the fuel cell unit (200). In addition, the domestic power plant has a storage battery unit (450) which is preferably arranged within the housing (550) and is integrated into the exhaust air tract (30) such that undesired gas released in the storage battery unit (450) is diluted by the air volume flow and can be removed together with waste heat from the storage battery unit (450). In addition, the domestic power plant has a second air tract (20) which is connected to the exhaust air tract (30), wherein the second air tract (20) of the ventilation device (12) is thermally coupled to the first air tract (14) via the heat exchanger (34) of the ventilation device (12) such that it is possible, via the second air tract (20), for expelled exhaust air to give off, as required and via the heat exchanger (34) of the ventilation device (12), at least part of the thermal energy contained therein to the first air tract (14), and simultaneously the undesired gases diluted by the air volume flow can be expelled together with the air volume flow via the external air connection (16), and as a result the formation of explosive gas mixtures in the domestic power plant is avoided and the domestic power plant can be operated safely.
