Alert method relating to remaining fuel amount of fuel cell system and fuel cell system using the same

摘要

An alert method capable of preventing problems due to excessive lowering of a remaining fuel amount of a fuel cell system is provided. The alert method includes the following steps of: switching over operation/stopped states of the fuel cell system, detecting that the state of the fuel cell system is switched over to a stopped side, and communicating information related to the remaining fuel amount to a user when fuel of the fuel cell system is consumed in a state where the switch is switched over to a stopped side. According to the alert method, information related to the remaining fuel amount is communicated to the user when fuel is consumed by the fuel cell system while in a practically stopped state. Therefore, it is possible to prevent excessive lowering of the remaining fuel amount of the fuel cell system.
