Abstract
A fuel cell system having a redundant voltage monitoring system for monitoring the voltage which is present on a fuel cell unit, and a method for voltage monitoring.
Claims17
A method for voltage monitoring for a fuel cell system having a fuel cell unit, with the fuel cell unit being connected via cables to an electrical component, said method comprising the steps:
- determining a voltage on the electrical component;
- producing a first actual value and a second, redundant actual value from the determined voltage which is present on the electrical component;
- and
- comparing at least one of the first actual value with a first limit value, and the second actual value with a second limit value.
