Abstract: Methods for operating an electrolysis system that includes an electrolyzer for generating hydrogen and oxygen as product gases, a product gas flow being formed in a phase mixture including water and a respective product gas with a content of a foreign gas are provided. A rotation is impressed upon at least one product gas flow such that a phase separation of water and product gas is produced in the phase mixture, wherein the product gas is supplied to a catalytically active zone such that foreign gas is recombined with the product gas in order to form water, and after flowing through the catalytically active zone, the product gas released from the foreign gas is mixed with the liquid phase again in order to form a phase mixture.

Abstract: The present invention includes an apparatus for determining and/or monitoring a process variable, especially the temperature, or the flow, of a medium in a containment, including a temperature sensor for registering temperature and a flexible, a heat insulating support element, which is arrangeable on an outer surface of a wall of the containment, wherein the temperature sensor is secured to the support element.

Abstract: A motor vehicle with a wheel, a wheel case enveloping the wheel, and an air duct leading to the wheel case, wherein the air duct incorporates an adjustable element, which in a first position steers the air entering into the wheel case through the air duct into a gap between an inner flank of the wheel and an inner wall of the wheel case, and in a second position diverts the air by an outer flank of the wheel.
