Device for detecting pressure in gas stream flowing in line element, has pressure sensor with sensor diaphragm, where surface of sensor diaphragm is aligned in direction of central axis of line part that is connected with line element

摘要

The device (21) has a pressure sensor (22) with a sensor diaphragm, where the pressure sensor is arranged in a side closed line part (23) that diverts the gas stream. The surface of the sensor diaphragm is aligned in the direction of a central axis (25) of the line part. The side sealed line part is connected with a line element (9,10,15,17) through a connecting line (24). The central axis of the side closed line part is aligned vertical to the gas stream in the intended insert in the area of the pressure sensor or the connecting line. The pressure sensor is rested above the gas stream. An independent claim is included for a fuel cell system with an anode side for supplying and discharging a gas stream in fuel to a fuel cell.
