Abstract: The invention relates to a method for line pressure monitoring, in particular for detecting leaks, in a bidirectionally used line section (40a) of a connection line unit (40) in an energy system (10), in particular in a domestic energy system, as well as an energy system (10) of this type, wherein a first energy source unit (21) and a first energy sink unit (22) are positioned on the first side (43) of the bidirectional line section (40a), and wherein a second energy source unit (31) and a second energy sink unit (32) are positioned on the second side (44) of the bidirectional line section (40a). In order to provide a secure monitoring of a bidirectional line, according to the invention, using two pressure measuring devices (50, 51) positioned spatially separate from one another in the bidirectional line section (40a), a first pressure (P1) and a second pressure (P2) present at the locations of the pressure measuring devices (50, 51) are detected, and, in particular in a control device (60) of the energy system (10), a monitoring of the line pressure in the bidirectional line section (40a) is carried out by means of an evaluation of the pressures (P1, P2) detected by the pressure measuring devices (50, 51), wherein the detected pressures (P1, P2) are placed in relation to one another in different ways.

Abstract: A fuel cell fluid discharge system, a fuel cell system, and a method for discharging byproducts produced during fuel cell operation are provided. The fluid discharge system comprises an inlet port, a discharge port, and a vessel. The vessel comprises a vessel port and an adjustable wall. The adjustable wall forms a fluid tight seal between a first volume within the vessel partially bounded by a first side of the adjustable wall, and a second volume of the vessel partially bounded by a second side of the adjustable wall. Moving the adjustable wall from a second position to a first position draws fluid through the inlet port into the first volume. Moving the adjustable wall from the first position to the second position expels fluid through the discharge port from the first volume at a pressure greater than a reactant pressure of the fuel cell.
