摘要： A control apparatus for a fuel cell stack having an operation control module is provided. The operation control module is configured in terms of programming and circuitry in order to control a large number of sensor or actuator systems that are relevant to normal operation. The sensor or actuator systems relate to the operating state of the fuel cell stack during normal operation and have a safety control module that is designed in terms of programming and circuitry to control safety-relevant sensor or actuator systems. The safety-relevant sensor or actuator systems relate to the safety functions of the fuel cell stack and the safety control module is in the form of an assembly which operates autonomously with respect to the operation control module. A method for controlling the fuel cell stack and the operation control module is also provided.

摘要： A measuring device to measure the insulation resistance (Riso) of a fuel cell system with respect to an electrical ground point comprises a resistor arrangement—formed by a series connection of reference resistors—between two load-current lines of the fuel cell system as well as one reference voltage source, which is arranged between the ground point and a node between the reference resistors and which is switchable between at least two different reference voltages (Urefo, Urefu). The measuring device further comprises one voltage-sensing device that acquires the voltage (Uo, Uu) between at least one of the load-current lines and the ground point. Connected to the voltage-sensing device is an evaluation unit, which determines the insulation resistance (Riso) on the basis of a first voltage value, which represents a value of the voltage between a first of the load-current lines and the ground point while a first reference voltage (Urefo) of the reference voltage source is applied, and on the basis of a second voltage value, which represents the value of the voltage between the first load-current line and the ground point while a second reference voltage (Urefu) of the reference voltage source is applied.
