Abstract
Disclosed is a fuel cell system and a method for controlling the same which in a constant current operation mode in which an output current of a fuel cell stack is constant, controls a hydrogen supply unit, an air supply unit, or a hydrogen recirculation unit differently depending on the size of a target output current to prevent the local flooding of the fuel cell stack in the constant current operation mode.
Claims16
A fuel cell system comprising:
- a fuel cell stack that comprises an anode to which hydrogen is supplied, a cathode to which air is supplied, and a membrane electrode assembly (MEA) between the anode and the cathode;
- a hydrogen supply unit that is configured to supply hydrogen to the anode;
- an air supply unit that is configured to supply air to the cathode;
- a hydrogen recirculation unit that is connected to the anode to recirculate discharged hydrogen from an outlet to an inlet;
- and
- a control unit that in a constant current operation mode in which an output current of the fuel cell stack is constant, is configured to control the hydrogen supply unit, the air supply unit, or the hydrogen recirculation unit differently depending on a size of a target output current to prevent local flooding of the fuel cell stack in the constant current operation mode.
