Abstract
The device and the method determine the temperature in a fuel cell installation. The temperature is recorded at least at one measurement location, such as a position and/or an region of a fuel cell stack and/or of a fuel cell unit, and is transmitted to a computation unit for a model computation. The computation unit then determines the temperature distribution in the stack with the aid of a model computation and transmits the information to a control unit. The control unit can be used to control the temperature in the stack.
Claims15
In an HTM fuel cell installation, a device for determining a temperature in the HTM fuel cell installation, comprising:
- a temperature detection device disposed to record a temperature of at least one measurement location in the HTM fuel cell installation;
- a computation unit for model computation connected to said temperature detection device and receiving a signal from said temperature detection device;
- said computation unit being programmed to determine a temperature distribution in the HTM fuel cell installation with a model computation;
- and
- a control unit connected to said computation unit, said control unit regulating at least one parameter of the HTM fuel cell installation selected from the group consisting of an HTM fuel cell voltage, a process-gas supply, a process-gas temperature, a process-gas composition, a quantity of coolant, a coolant composition, and a coolant temperature.
A method of dynamically controlling a fuel cell installation, which comprises:
- determining at least one process parameter in an HTM fuel cell installation, the parameter selected from the group consisting of a temperature of an HTM fuel cell and a composition of a process gas;
- transmitting information of the process parameter to a control unit as an input actual value;
- comparing, with the control unit, at least one input actual value with a predetermined desired value and actuating at least one corresponding control device of the fuel cell installation such that the actual value is made to approach the desired value.
