Title: FUEL CELL SYSTEM AND METHOD OF CONTROLLING FUEL CELL SYSTEM
Abstract:
A fuel cell system (100) is equipped with an airflow meter (33) that measures an amount of a supplied cathode gas, and a hydrogen circulation pump (64). A controller (20) instructs the fuel cell (10) to perform a preset reference operation, measures the power consumed by the hydrogen circulation pump (64), and determines the amount of the supplied cathode gas appropriate for the amount of power consumed by the hydrogen circulation pump (64). The controller (20) then calculates, the measurement error in the airflow meter (33) and correction value for the measurement error. The controller (20) controls the amount of the supplied cathode gas based on the value measured by the airflow meter (33) after being corrected with the correction value.
