摘要： A hydraulic cylinder, in particular for a hydrogen tank pressurization installation, including a cylindrical body of longitudinal axis having a first low-pressure cylindrical body portion and a second high-pressure cylindrical body portion, a piston being mounted in the first cylindrical body portion and being mounted at a first end of a piston rod slidably extending in the second cylindrical body portion. A second end of the rod opposite the first end carries a removable cartridge slidably sealed in the second part of the cylindrical body, the second part of the cylindrical body being sealed by a removable shutter member arranged longitudinally opposite the removable cartridge.

摘要： The invention relates to a fuel cell membrane handling device comprising a first membrane storage station (A1) and a receiving station (C) as well as a first manipulator (B1) comprising means (68) for gripping a membrane (12) from a free face thereof, the first manipulator (B1) being articulated so as to be capable of moving between a position for taking a membrane (12) from the storage station (A1) and a position for placing a membrane (12) in the receiving station (C). According to the invention, the receiving station (C) comprises a tray for receiving a membrane (12) comprising at least one opening (C2) wherein the gripping means (68) and a portion of the manipulator are capable of fitting into a first position for placing a membrane (12) wherein the membrane (12) is received on the receiving tray (C1).
