What is claimed is: 1. A fuel cell system comprising: a fuel tank configured to store a fuel at a pressure higher than atmospheric pressure; a reformer configured to reform the fuel into a hydrogen rich gas; a water tank configured to store water to be supplied to the reformer, being coupled to the fuel tank; a vaporizer configured to vaporize the water in the water tank; a CO gas removal apparatus configured to remove CO gas in the hydrogen rich gas; and a cell unit configured to generate electricity by allowing the hydrogen rich gas to react with oxygen, wherein the water tank includes a first chamber coupled to an upper part of the fuel tank; a second chamber coupled to an upstream of the vaporizer; and a partition disposed between the first chamber and the second chamber. 2. A fuel cell system comprising: a fuel tank configured to store a fuel at a pressure higher than atmospheric pressure; a reformer configured to reform the fuel into a hydrogen rich gas; a water tank configured to store water to be supplied to the reformer, being coupled to the fuel tank; a vaporizer configured to vaporize the water in the water tank; a CO gas removal apparatus configured to remove CO gas in the hydrogen rich gas; a cell unit configured to generate electricity by allowing the hydrogen rich gas to react with oxygen, the cell unit including: a fuel electrode being supplied with the hydrogen rich gas; an air electrode being supplied with oxygen so as to react with hydrogen rich gas and to generate electricity; and a polymer film interposed between the fuel electrode and the air electrode; and a first oxygen supply unit configured to supply oxygen to the cell unit, the first oxygen supply unit including: a first chamber coupled between the CO gas removal apparatus and a fuel electrode of the cell unit; a second chamber connected to an air electrode of the cell unit; and a partition disposed between the first chamber and the second chamber. 3. The fuel cell system of claim 2, further comprising a heat pipe interposed between the first oxygen supply unit and the cell unit. 4. The fuel cell system of claim 2, further comprising a fluid cylinder located at an upstream side of the first chamber. 5. The fuel cell system of claim 4, wherein a surface area of a second partition disposed in the fluid cylinder is smaller than the partition disposed in the oxygen supply unit. 6. The fuel cell system of claim 2, wherein a first buffer tank is coupled to an upstream side of the first chamber and a second buffer tank is coupled to a downstream side of the second chamber. 7. The fuel cell system of claim 2, wherein a check valve is coupled to the second chamber.
