A coupler for a fuel cell has a socket provided to the fuel cell and having a valve (40) and urging means for urging the valve (40) in the direction in which the valve (40) is closed, and also has a nozzle provided to a fuel cartridge, which receives liquid fuel for the fuel cell, and having a valve and urging means for urging the valve in the direction in which the valve is closed. The coupler connects the socket and the nozzle to each other to cause the valves (40) to make contact with each other to open the valves, and the coupler is used to supply the liquid fuel, received in the fuel cartridge, to the fuel cell. The coupler is constructed such that at least one (40) of the valves on the socket side and the nozzle side has both a head (40a) and rods (40b, 40c) arranged at opposite ends axially of the head (40a) and such that the rod (40b) on the contacting side is mainly constructed from a metal member.
