Monitoring Apparatus for a Fuel Cell Stack
First Claim
1. A control apparatus for a fuel cell stack, said control apparatus comprising:
- an operations control module, wherein the operations control module is configured, in terms of program technology or circuit technology, to control a plurality of normal-operation-related sensor systems or actuator systems, wherein the normal-operation-related sensor systems or actuator systems relate to the operating state of the fuel cell stack during normal operation, anda safety control module, wherein the safety control module is configured, in terms of program technology or circuit technology, to control safety-related sensor systems or actuator systems, wherein the safety-related sensor systems or actuator systems relate to the safety functions of the fuel cell stacks, andwhereinthe safety control module is provided as an assembly which operates in an autonomous fashion with respect to the operations control module.

Abstract
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.
