A fuel cell system that employs an oxygen sensor for measuring the oxygen concentration in the cathode exhaust gas from the fuel cell stack. A controller provides a signal that drives a compressor providing air to a cathode input of the stack so that the compressor provides the desired oxygen to achieve the desired cathode lambda. In one embodiment, the fuel cell system also employs an airflow meter that measures the amount of air being applied to the compressor. The controller compares the oxygen input applied to the stack to the oxygen output from the stack for diagnostic purposes, such as determining the presence of leaks. A temperature sensor can be employed to measure the temperature of the cathode exhaust and a pressure sensor can be employed to measure the pressure of the cathode exhaust to compensate for water vapor in the cathode exhaust.
