  The above host compounds may be used individually by 1 type, and may use 2 or more types together. The host compound may be any form of compound as long as it forms a solid clathrate compound with the fuel for the fuel cell.

  As a method of synthesizing a fuel cell fuel clathrate compound using a host compound such as 1,1-bis (4-hydroxyphenyl) cyclohexane described above, the fuel cell fuel and the host compound are directly contacted and mixed. In addition, for example, it can also be obtained by a method in which a host compound is dissolved in a fuel for a fuel cell and recrystallized under heating. Further, when the fuel for the fuel cell is a gas or liquid, it can be obtained by contacting the fuel with the host compound in a pressurized state.

  The temperature at which the fuel for the fuel cell is brought into contact with the host compound is not particularly limited, but is preferably from room temperature to about 100 ° C. The time for contacting the fuel cell fuel with the host compound is not particularly limited, but is preferably about 0.01 to 24 hours from the viewpoint of work efficiency.

  The fuel for the fuel cell to be brought into contact with the host compound is preferably a high-purity fuel. However, when a host compound having the selective inclusion ability of the fuel for the fuel cell is used, the fuel for the fuel cell and other components It may be a mixed liquid.

  The clathrate compound thus obtained varies depending on the type of the host compound used, the contact conditions with the fuel for the fuel cell, etc., but usually 0.1 to 10 fuel molecules for the fuel cell per mole of the host compound. It is an clathrate compound that clathrates a mole.

  The clathrate compound can stably store fuel for a fuel cell for a long period of time in a normal temperature / normal pressure environment. Moreover, since this inclusion compound is lightweight and excellent in handleability and is solid, it can be easily stored in a container such as glass, metal, plastic, etc., and the problem of liquid leakage is also eliminated. . In addition, since the liquid fuel is usually solidified by inclusion, the property as a deleterious substance or a dangerous substance can be avoided. Furthermore, the chemical reactivity of the fuel for the fuel cell can be reduced, and for example, the corrosiveness to metals can be alleviated. Thus, the fuel for fuel cells stabilized as an inclusion compound is easy to handle and is suitable as a product in the mail order system according to the present embodiment.

  As a method for removing the fuel cell fuel from the state in which the fuel cell fuel is stored in the clathrate compound, the clathrate compound is obtained by bringing the solid clathrate compound of the fuel cell fuel into contact with water or an aqueous fuel cell fuel solution. The fuel cell fuel can be taken out by discharging it to water or the fuel cell fuel aqueous solution side. Moreover, the fuel for fuel cells can also be taken out by heating.
