Abstract
A fuel cell system executes charge processing to charge electric power generated by a stack to a battery, and sealed discharge processing to cause an oxygen concentration inside a cathode flow channel to decrease, after a stop operation has been made on a power switch. The stop method of a fuel cell system includes: a step of calculating a remaining charge time corresponding to a time in which charge processing can be executed, by subtracting a time required in sealed discharge processing from a predetermined stop processing permitted time, after a stop operation has been made on the power switch (Step S), a step of calculating a remaining target charge amount of the battery (Step S), a step of executing charge processing while controlling output of the stack based on the remaining charge time and remaining target charge amount (Step S), and a step of executing sealed discharge processing.
