Abstract: Matrix cells are used for regeneration in an electrolyzer system. The electrolyte is electrolyzed in the matrix cell. Gas (predominantly product gas) which has unwantedly accessed the electrolyte space is transported off from the electrolyte space into the gas space envisioned therefor by a degassing device. Additional measures such as ultrasonic transducers and field electrodes may realize electrolyte flow and improved transporting-off of gas. A pump may be used to move the electrolyte, and the pump may move the electrolyte by generating bubbles.

Abstract: A bipolar plate for use in an electrochemical device is proposed, in which a flow duct runs between two outer boundary surfaces and extends from a peripheral fluid inlet to a peripheral fluid outlet. As a result, very good cooling of electrochemical cells via a bipolar plate which is in surface contact therewith can be achieved.

Abstract: A power semiconductor circuit comprising a field effect transistor having a drain, a source and a gate as terminals, and further comprising a control device having a drive device and an undervoltage detection circuit. The drive device drives the field effect transistor and is electrically connected to the gate of the field effect transistor. The undervoltage detection circuit generates an undervoltage detection signal if a power semiconductor voltage present between the drain and the source of the field effect transistor falls below a specific voltage value. The drive device switches on the field effect transistor when a switch-on command for switching on the field effect transistor and the undervoltage detection signal are present. The invention provides a power semiconductor circuit with low energy loss.

Abstract: A liquid redistributor, arranged in a packing column between two packings, wherein in the column a liquid phase is guided from top to bottom and against the same a gas phase from bottom to top, comprising a liquid distributor tray and a droplet damping tray, which attenuates the fluidization of the liquid layer on the liquid distributor tray as caused by the droplets falling down.
