摘要: The highly reliable hydrogen impurity testing system includes a sensor unit installed in an atmosphere with highly concentrated hydrogen containing toxic impurities, a heater unit capable of heating the sensor unit, and a system controller controlling the sensor unit and the heater unit. The heater unit includes a semiconductor substrate, an impurity layer of a first conductive type, a metal oxide layer, and a metal electrode layer capable of adsorbing toxic impurities being present on the surface of the metal oxide layer. The system controller detects the concentration of the toxic impurities by measuring the change in work function of the metal electrode layer according to the type and concentration of the toxic impurities, and performs a refreshing operation of desorbing the toxic impurities adsorbed on the metal electrode layer by heating the metal electrode layer with the heater unit based on the result of detection.

摘要: The present invention relates to a fuel cell system (100) for providing electrical energy. The fuel cell system (100) comprises a blower (101) for conveying anode gas, a movement sensor (103) for detecting measurements of a movement of a paddle wheel of the blower (101), and a controller (105). The controller (105) is configured to assign a state of a composition of matter in an anode circuit of the fuel cell system (100) to measured values of the blower (101) detected by the motion sensor (103) in a speed range between a start speed and a predetermined target speed using a predetermined assignment scheme, and to adjust the fuel cell system (100) depending on the assigned state.
