Title:
DEVICE FOR PROVIDING HYDROGEN
Document Type and Number:
WIPO Patent Application WO/2023/217683
Kind Code:
A3
Abstract:
In order to provide a device (1) for providing hydrogen (H2) by means of an electrolysis unit (2) which allows the longest possible service life of the electrolysis unit (2) even in case of fluctuating energy supplies to the electrolysis unit (2), a reciprocating piston compressor (3) is provided to compress the hydrogen (H2) generated by the electrolysis unit (2), the reciprocating piston compressor (3) having at least one automatic intake valve (5). A retraction gripper (6) is provided in order to hold the intake valve (5) selectively in an open position, an electrically actuatable actuator (7) is provided to activate the retraction gripper (6), and a control unit (4) is provided to control the actuator (7), the control unit (4) being designed to actuate the actuator (7) in such a way that an outlet pressure (p1) of the hydrogen (H2) at the outlet of the electrolysis unit (2), or a differential pressure (Δp) between an anode and a cathode of the electrolysis unit (2), is adjustable to a predefined target value (p1_soll, Δp_soll).
