Abstract: An enclosed separator unit for incorporation into a gas supply device of a fuel cell system, to separate liquid from the gas supply device, includes a separator for separating the liquid. A housing encloses the separator unit which is arranged in a gas space 21 in the housing and/or is in thermal contact with the gas space. A line system is provided for discharging the liquid from the separator, and at least one fluid dynamically active functional component is arranged in the line system, in the gas space 21.

Abstract: A vehicle drive system comprises an electrical drive motor and a fuel cell system providing the electrical power. According to the invention, the drive motor and the fuel cell are integrated into a unit and firmly joined together. The fuel cell system may comprise two fuel cells or fuel cell stacks, which are arranged relative to each other so as to form a “V”. Peripheral units for operation of the fuel cell may be arranged in an interior of the V.

Abstract: In a temperature sensor with a platinum resistance thermometer accommodated in a tube-shaped housing, the platinum resistance layer belonging thereto should be protected against pollution or contamination of the platinum, since the electrochemical characteristics of platinum can be reduced by substances in the surroundings in the event of too low a partial pressure of oxygen. For this purpose, a mechanically solid and liquid-impermeable, connection is provided in the connection region of the tube-shaped housing, which permits an admission of air-oxygen into the housing from the environment of the connecting cable. The air-oxygen admission is made possible through a liquid-impermeable oxygen-permeable jacket for the connecting cable and/or over an accompanying connecting plug, whereby the admission of air-oxygen takes place along a glass filament filler running parallel to the electrical leads inside the jacket of the connecting cable.
