1. A mobile machine, comprising: at least one tank to carry fuel that is in a gaseous state under normal conditions, wherein the tank is made of a ferrous metal and defines a unitary base body having an integral, one piece metal block shape with a substantially rectangular external contour in three cross-sectional planes that are perpendicular to one another;at least one interior pressure chamber monolithically formed by an internal contour of the base body, wherein the interior pressure chamber has a substantially circular cross section in at least one cross-sectional plane; andat least one closing element connectable to the base body to seal said at least one interior pressure chamber. 2. The mobile machine as claimed in claim 1, wherein said pressure chamber of the tank is provided with a coating. 3. The mobile machine as claimed in claim 1, wherein the closing element comprises at least one fitting or at least one connecting device for at least one fitting or pipe. 4. The mobile machine as claimed in claim 3, wherein the base body of the tank comprises at least one connecting device for at least one fitting or at least one pipe. 5. The mobile machine as claimed in claim 1, wherein the base body of the tank comprises at least one connecting device for at least one fitting or at least one pipe. 6. The mobile machine as claimed in claim 1, wherein the tank has at least two separate pressure chambers formed by internal contours of the base body. 7. The mobile machine as claimed in claim 1, wherein the tank includes devices for fastening the tank to the mobile machine or to additional tanks. 8. The mobile machine as claimed in claim 1, wherein the tank is provided for the storage of hydrogen. 9. The mobile machine as claimed in claim 1, wherein the tank is made of steel. 10. A pressurized tank for a mobile machine, comprising: a unitary base body made of steel and having an integral, one piece metal block shape with a substantially rectangular external contour in three cross-sectional planes that are perpendicular to one another;at least one interior pressure chamber monolithically formed by an interior contour of the base body and having a substantially curved cross section in at least one cross-sectional plane; andat least one closing element connectable with the base body to seal the at least one pressure chamber. 11. The mobile machine as claimed in claim 10, wherein said pressure chamber of the tank is provided with a coating. 12. The mobile machine as claimed in claim 10, wherein the closing element comprises at least one fitting or at least one connecting device for at least one fitting or pipe. 13. The mobile machine as claimed in claim 10, wherein the tank has at least two separate pressure chambers.
