FUEL CELL SYSTEM AND CONTROL METHOD OF FUEL CELL SYSTEM

摘要

In order to provide a fuel cell system that inhibits the occurrence of degradation of an MEA while also inhibiting an increase in the CPU load. A fuel cell system is equipped with a hydrogen supply unit that supplies hydrogen to a fuel cell, a pressure detection unit that detects the internal pressure of hydrogen supply piping, a current detection unit that detects the current value of the fuel cell, and a control unit that calculates the necessary hydrogen supply volume for the fuel cell based on the detected current value and pressure value, and controls the hydrogen supply unit to supply hydrogen corresponding to the calculated hydrogen supply unit to the fuel cell, wherein the control unit calculates the hydrogen supply volume based on the pressure value and the current value for each of a first cycle, and acquires the pressure value and supplies hydrogen corresponding to the immediately prior calculated hydrogen supply volume to the fuel cell when the control unit is determined that supply of hydrogen is necessary based on the acquired pressure value, for each of a second cycle which shorter than the first cycle.
