FUEL SUPPLY DEVICE AND FUEL CELL SYSTEM

PROBLEM TO BE SOLVED: To provide a fuel supply device which can supply smoothly liquid fuel from an external fuel supply source such as a cartridge to a fuel cell body being a passive type fuel cell which does not use auxiliary equipment such as a pump and a secondary battery, and in which the liquid fuel contained does not leak to the outside even if a non-usage period is long, and a fuel cell system. SOLUTION: The fuel supply device includes a fuel filling port 20 which has a structure in which the fuel supply source can be connected liquid-tightly and has a reverse-flow prevention function to prevent the liquid fuel from returning to the fuel supply source, movable chambers 16, 16B which communicate with the fuel filling port and contain the liquid fuel filled through the fuel filling port, pressurizing mechanisms 14, 17 which pressurize the movable chamber, and a fuel exit 12 which communicates with the movable chambers and sends out the liquid fuel from the movable chambers to the fuel cell body having a power generation mechanism.
