A process for determining the DC current in a fuel cell power plant
includes the steps of determining current value from a power electronics
converter of a power conditioning system of the power plant; determining
a correction factor based upon losses within the converter; and
correcting the current value from the converter with the correction
factor to determine DC current in the fuel cell. This process also
includes determining voltage within the converter and use of the voltage
along with the corrected current to determine the desired DC current
value.
