What is claimed is: 1. A fuel reservoir for a fuel cell detachably connected with a fuel cell main body, wherein: the fuel reservoir is equipped with a fuel-storing vessel for storing a liquid fuel and a fuel discharge part; the fuel discharge part is equipped with a valve for sealing communication
What is claimed is: 1. A fuel reservoir for a fuel cell detachably connected with a fuel cell main body, wherein: the fuel reservoir is equipped with a fuel-storing vessel for storing a liquid fuel and a fuel discharge part; the fuel discharge part is equipped with a valve for sealing communication between the inside and the outside of the fuel-storing vessel; the inside of the fuel-storing vessel is communicated with the fuel cell main body by inserting a liquid fuel-supplying member into the valve, thereby forming a communication part that communicates the inside of the fuel-storing vessel with the fuel cell main body and through which the liquid fuel in the inside of the fuel-storing vessel is supplied to the fuel cell main body; the valve comprises an elastic material and has an elliptic form in a cross section; the communication part is a slit which is provided in a minor axis direction of the ellipse, wherein the valve is pressed into a circular vessel having a shorter diameter or an elliptic vessel having a shorter major axis than the major axis of its ellipse to compress its own major axis direction. 2. A fuel reservoir for a fuel cell detachably connected with a fuel cell main body, wherein: the fuel reservoir is equipped with a fuel-storing vessel for storing a liquid fuel and a fuel discharge part; the fuel discharge part is equipped with a valve for sealing communication between the inside and the outside of the fuel-storing vessel; the inside of the fuel-storing vessel is communicated with the fuel cell main body by inserting a liquid fuel-supplying member into the valve, thereby forming a communication part that communicates the inside of the fuel-storing vessel with the fuel cell main body and through which the liquid fuel in the inside of the fuel-storing vessel is supplied to the fuel cell main body; the valve comprises an elastic material and has a circular form in a cross section; the communication part is a slit which is provided in a diameter direction of the circle, wherein the valve is pressed into an elliptic vessel having a shorter minor axis than a diameter of the valve so that a line formed by the slit is consistent with a major axis direction of the ellipse. 3. The fuel reservoir for a fuel cell as described in claim 1, wherein the vessel into which the valve is pressed is a valve-receiving part provided in the fuel-storing vessel. 4. The fuel reservoir for a fuel cell as described in claim 1, wherein the vessel into which the valve is pressed is a valve adaptor, and a composite in which the valve is installed in the valve adaptor is loaded in the fuel-storing vessel. 5. The fuel reservoir for a fuel cell as described in claim 1, wherein the valve comprises a material having low gas permeability toward the liquid fuel and comprises a material having a compression set of 20% or less prescribed in JIS K 6262-1997. 6. The fuel reservoir for a fuel cell as described in claim 5, wherein the material of the valve is selected from the group consisting of butyl rubber, halogenated butyl rubber and acrylonitrile-butadiene rubber. 7. The fuel reservoir for a fuel cell as described in claim 1, wherein a convex projection is formed in the valve toward the inside of the fuel-storing vessel. 8. The fuel reservoir for a fuel cell as described in claim 1, wherein the liquid fuel is at least one selected from the group consisting of a methanol solution, an ethanol solution, dimethyl ether, formic acid, hydrazine, an ammonia solution, ethylene glycol, a saccharide aqueous solution and a sodium boron hydride aqueous solution. 9. The fuel reservoir for a fuel cell as described in claim 1, wherein the fuel cell main body assumes a structure in which plural unit cells each of which is formed by constructing an electrolyte layer on the outer surface of a fuel electrode body and constructing an air electrode layer on the outer surface of the electrolyte layer are joined and in which the fuel-supplying member connected with the fuel reservoir is connected with the unit cells to supply the liquid fuel. 10. The fuel reservoir for a fuel cell as described in claim 2, wherein the vessel into which the valve is pressed is a valve-receiving part provided in the fuel-storing vessel. 11. The fuel reservoir for a fuel cell as described in claim 2, wherein the vessel into which the valve is pressed is a valve adaptor, and a composite in which the valve is installed in the valve adaptor is loaded in the fuel-storing vessel. 12. The fuel reservoir for a fuel cell as described in claim 2, wherein the valve comprises a material having low gas permeability toward the liquid fuel and comprises a material having a compression set of 20% or less prescribed in JIS K 6262-1997. 13. The fuel reservoir for a fuel cell as described in claim 12, wherein the material of the valve is selected from the group consisting of butyl rubber, halogenated butyl rubber and acrylonitrile-butadiene rubber. 14. The fuel reservoir for a fuel cell as described in claim 2, wherein a convex projection is formed in the valve toward the inside of the fuel-storing vessel. 15. The fuel reservoir for a fuel cell as described in claim 2, wherein the liquid fuel is at least one selected from the group consisting of a methanol solution, an ethanol solution, dimethyl ether, formic acid, hydrazine, an ammonia solution, ethylene glycol, a saccharide aqueous solution and a sodium boron hydride aqueous solution. 16. The fuel reservoir for a fuel cell as described in claim 2, wherein the fuel cell main body assumes a structure in which plural unit cells each of which is formed by constructing an electrolyte layer on the outer surface of a fuel electrode body and constructing an air electrode layer on the outer surface of the electrolyte layer are joined and in which the fuel-supplying member connected with the fuel reservoir is connected with the unit cells to supply the liquid fuel.
