PULSATING OPERATION METHOD AND SYSTEM FOR FUEL CELL SYSTEM

摘要

A pulsating operation method and system for a fuel cell system that smoothly discharges water remaining in a fuel electrode of a fuel cell and, simultaneously, improves fuel utilization. The method includes performing a pulsation control that controls the magnitude and period of a pulsating operating pressure for hydrogen supplied to an anode of a fuel cell to smoothly discharge the water remaining in the anode, maximize fuel utilization of the anode, and improve operational stability of the fuel cell system.

1. A pulsating operation method for a fuel cell system, the method comprising:
performing, by a controller, a pulsation control that controls a magnitude and a period of a pulsating operating pressure for fuel supplied to an anode of a fuel cell during an opening period of a hydrogen purge valve connected to an anode outlet to maintain water discharge in the anode and fuel utilization of the anode.
