Abstract: System and methods for measuring operating parameters of a fuel cell system are presented. In certain embodiments, the systems and methods may be configured to measure a high frequency resistance of a fuel cell system. A method for measuring a high frequency resistance of a fuel cell system may include inducing a current signal and a voltage signal through the FC system at a center frequency using a switched load. The current signal and the voltage signal may then be measured and filtered to isolate the current signal and the voltage signal from noise signals occurring in the FC system. A high frequency resistance of the FC may then be calculated based on the filtered current and voltage signals.
