Embodiment Construction

[0041] With reference to the drawings, description will be given below of a coupler according to an embodiment of the present invention.

[0042]FIG. 1 shows the configuration of a fuel cell coupler K in a position in which, for example, a cell solution S is supplied.

[0043] Reference numeral 1 at the bottom of FIG. 1 denotes a cell container (solution tank) constituting a fuel cell. Reference numeral 2 at the top of FIG. 1 denotes a supply container (liquid retaining container) in which the cell solution S is stored. When the cell solution S from the supply container 2 is supplied to the cell container 1, the supply container 2 takes a position shown in FIG. 1. However, in a normal state, the supply container 2 is maintained in a position in which it is turned upside down.

[0044] An injection port 3 is projected from the upper end of the cell container 1. A supply port 4 is projected from the lower end of the supply container 2 in FIG. 1. A female coupler 5 is attached to the injection
