Coupling holding means 50 comprising retainers 53 and retainer engaging portions 52 for holding a coupled state is provided between a socket S10 and a plug P10 of a coupler. Engaging pawl portions 54 are formed on the inner sides of a pair of retainers 53 provided on both sides of a nozzle portion 32. By causing the retainers 53 to move outwardly in a coupling operation, a gap between the retainers 53 and the nozzle portion 32 can be made small. By forming interference preventing portions 58 in the engaging pawl portions 54, the retainers 53 can be provided at a smaller interval than the outer diameter of the nozzle portion 32 whereby the coupler can be made even more compact. Further, by forming the retainers 53 higher than the foremost end portion of the nozzle portion 32, the nozzle portion 32 can be protected by the retainers 53 even in an unexpected event such as falling and damage will not extend directly to the nozzle portion 32.

A coupler (1) for a fuel cell according to the embodiment has a socket (1s) and a nozzle (1n). The socket (1s) is provided to the fuel cell (2) and has a valve (40). The nozzle (1n) is provided to a fuel cartridge (3) for storing a liquid fuel for the fuel cell (2) and has a valve (14). The coupler (1) supplies the liquid fuel stored in the fuel cartridge (3) to the fuel cell (2) by opening both the valves (14, 40) by contacting mutually when the socket (1s) and the nozzle (1n) are connected. At least one valve selected from the socket side and the nozzle side has a head section (14a or 40a) and rod sections (14b and 14c, or, 40b and 40c) arranged at opposite ends axially of the head section (14a or 40a), and the rod section (14b or 40b) on the contact side is mainly made of a metal member.

A nozzle part 9 provided in a fuel cartridge is inserted in a socket part 6 provided in a fuel cell body, and the nozzle part 9 and the socket part 6 are coupled. The nozzle part 9 has a nozzle head 12 provided on the cartridge body 8 and a valve mechanism arranged in this nozzle head 12. On a tip of the nozzle head 12, a spherical portion 15 is provided so as to detach from the socket part 6 without being interfered when a bending load is applied to the fuel cartridge 5 coupled to the fuel cell body.

In, for example, a direct methanol type fuelcell, fuel is allowed to be injected little by little when the fuel is injected and supplied from the outside to a fuel receiving part reduced in the amount of remaining fuel on the fuelcell body side and an electromotive part can be prevented from being damaged by keeping the pressure in the fuel receiving part at a fixed level or less when the fuel is injected. Specifically, when a fuel CL filled in a refuelling container C is injected into a fuel receiving part T in several lots, a fuel injecting operation is repeated in which the volume of the refuelling container C is shrunk and reduced to supply the fuel into the fuel receiving part T in a proper amount and then the original volume of the refuelling container is restored to thereby absorb the atmospheric gas in the fuel receiving part T, which makes it possible to inject fuel continuously without any hindrance to the injection of the fuel.
