Patent number: 10177390Abstract: In a method for controlling a fuel cell system, a shutoff valve is opened to supply a fuel gas from a storage container to a fuel cell after a fuel cell system shutdown instruction is sent to the fuel cell system so that the fuel cell generates and discharges electricity. The storage container is supplied to the fuel gas supplied from a fuel supply source provided outside the fuel cell system in response to a filling instruction to supply the fuel gas to the storage container. A data signal indicating a state of the storage container is transmitted to the fuel supply source. The shutoff valve is closed and the storage container is supplied to the fuel gas supplied from the fuel supply source if the filling instruction is output while opening the shutoff valve after the fuel cell system shutdown instruction is sent.Type: GrantFiled: March 25, 2014Date of Patent: January 8, 2019Assignee: HONDA MOTOR CO., LTD.Inventors: Go Kikuchi, Chihiro Wake, Yuji Matsumoto

Patent number: 9455462Abstract: In a method for deactivating a fuel cell system, low electric-power generation is performed prior to oxygen-consumption electric-power generation in a case where a state of charge in an electricity storage device provided in the fuel cell system is larger than a predetermined value when a stop switch provided in the fuel cell system is operated. After the state of charge in the electricity storage device is reduced to the predetermined value by compensating for a negative net output by discharging electricity from the electricity storage device, the oxygen-consumption electric-power generation in which oxygen remaining in a cathode system of the fuel cell is consumed to reduce oxygen concentration within the cathode system is performed.Type: GrantFiled: July 22, 2013Date of Patent: September 27, 2016Assignee: HONDA MOTOR CO., LTD.Inventors: Go Kikuchi, Chihiro Wake
