ABSTRACT:
A fuel cell system determines a water blockage or a dry state of the system using voltage sensors that determine anode and cathode voltages of single fuel cells as well as a total voltage for the fuel cell system. The system also compensates for water blockages or dry states by adjusting supplies of fuel and oxidation gases to the system.
