To reduce the amount of evaporated fuel adsorbed in an evaporated fuel processing device during fuel supply work.SOLUTION: A fuel tank system (1) is provided that comprises: a fuel tank (2) that stores liquid fuel for a fuel cell; fuel piping (3) which has a fuel supply port (3A) at one end thereof and is connected to the fuel tank (2) at the other end; an evaporated fuel processing device (5) which is connected to the fuel tank (2) via a communication passage (4) and adsorbs the evaporated fuel generated in the fuel tank (2); and a shutoff device (7) which is controlled to open and close by a control unit (17) and, when closed, shuts off the flow of evaporated fuel from the fuel tank (2) to the evaporate fuel processing device (5). The fuel supply port (3A) has a mechanism which can be hermetically connected to the spout (20A) of a portable fuel container (20), and the fuel piping (3) also functions as a device for collecting the evaporated fuel into the portable fuel container (20) since the shutoff device (7) is closed when supplied with fuel from the portable fuel container (20).SELECTED DRAWING: Figure 1

    【課題】燃料供給作業中における蒸発燃料の蒸発燃料処理装置への吸着量を低減する。【解決手段】燃料電池用の液体燃料を貯留する燃料タンク(2)と、一端に燃料供給口(3A)を備え、他端が燃料タンク(2)に接続された燃料配管(3)と、燃料タンク(2)に連通路(4)を介して接続され、燃料タンク(2)で生じた蒸発燃料を吸着する蒸発燃料処理装置(5)と、制御部(17)により開閉制御され、閉じた場合に燃料タンク(2)から蒸発燃料処理装置(5)への蒸発燃料の流れを遮断する遮断装置(7)と、を備える燃料タンクシステム(1)において、燃料供給口(3A)は、携行燃料容器(20)の注ぎ口(20A)と密閉連結可能な機構を有し、携行燃料容器(20)から燃料供給される場合には、遮断装置(7)が閉じることにより、燃料配管(3)が蒸発燃料を携行燃料容器(20)に回収する装置としても機能する。【選択図】図1
