System for feeding gaseous fuel, in particular hydrogen, for fuel cells which comprises a storage tank for the gaseous fuel of the type comprising a case containing a material absorbing the gaseous fuel, in particular a metal hydride, and means for applying an amount of heat to the material absorbin
System for feeding gaseous fuel, in particular hydrogen, for fuel cells which comprises a storage tank for the gaseous fuel of the type comprising a case containing a material absorbing the gaseous fuel, in particular a metal hydride, and means for applying an amount of heat to the material absorbing gaseous fuel and determining the flow of the gaseous fuel from the absorbing material towards an anode of one or more fuel cell. The storage tank and the one or more fuel cell are mutually arranged in such a way as to achieve a heat exchange relationship between the anode of one or more fuel cells and the gas absorbing material, the means for applying an amount of heat comprising the heat exchange between the anode of one or more fuel cells and the gas absorbing material.

The invention claimed is: 1. System for feeding gaseous fuel, in particular hydrogen, for fuel cells which comprises a storage tank for said gaseous fuel of the type comprising a case containing a material absorbing said gaseous fuel, in particular a metal hydride, and means for applying an amount of heat to said material absorbing gaseous fuel and for determining the flow of said gaseous fuel from said absorbing material towards an anode of one or more fuel cells, wherein said storage tank and said one or more fuel cells are mutually arranged in such a way as to achieve a heat exchange relationship between said anode of one or more fuel cells and said gas absorbing material, said means for applying an amount of heat comprising said heat exchange between said anode of one or more fuel cells and said gas absorbing material, and wherein said case of said storage tank contains at least in part said anode. 2. System as claimed in claim 1, wherein said anode comprises at least one wall in contact with said storage tank to achieve said heat exchange. 3. System as claimed in claim 2, wherein said wall comprises a porous baffle. 4. System as claimed in claim 1, wherein said case of said storage tank contains one or more fuel cells. 5. System as claimed in claim 4, wherein said one or more fuel cells comprise a cathode, containing a channel for the passage of a diathermic fluid, said cathode being contained within an electrolyte element, said electrolyte element being contained within said anode. 6. System as claimed in claim 5, wherein said case, said anode, said electrolyte element and said cathode have substantially hollow cylinder or tubular shape and are arranged coaxial to each other. 7. System as claimed in claim 1, wherein a pressure difference is applied between the storage tank and one or more fuel cells. 8. System as claimed in claim 2, wherein said system comprises a conduit for the flow of the gaseous fuel from the storage tank to the anode of the fuel cell. 9. System as claimed in claim 1, wherein said gaseous fuel is hydrogen. 10. System as claimed in claim 1, wherein said gas absorbing material is a metallic hydride, in particular Titanium Iron hydride or magnesium hydride. 11. System as claimed in claim 1, wherein said fuel cell is a Proton Exchange Membrane Fuel Cell or micro-cell and said gas absorbing material is titanium-iron hydride. 12. System as claimed in claim 1, wherein said fuel cell is an "alkaline" or "phosphoric acid" fuel cell and said gas absorbing material is magnesium hydride. 13. System for feeding gaseous fuel, in particular hydrogen, for fuel cells which comprises a storage tank for said gaseous fuel of the type comprising a case containing a material absorbing said gaseous fuel, in particular a metal hydride, and means for applying an amount of heat to said material absorbing gaseous fuel and for determining the flow of said gaseous fuel from said absorbing material towards an anode of one or more fuel cells, wherein said storage tank and said one or more fuel cells are mutually arranged in such a way as to achieve a heat exchange relationship between said anode of one or more fuel cells and said gas absorbing material, said means for applying an amount of heat comprising said heat exchange between said anode of one or more fuel cells and said gas absorbing material, wherein said anode comprises at least one wall in contact with said storage tank to achieve said heat exchange, and wherein said wall comprises a porous baffle. 14. System as claimed in claim 13, wherein said case of said storage tank contains at least in part said anode. 15. System as claimed in claim 14, wherein said case of said storage tank contains one or more fuel cells. 16. System as claimed in claim 13, wherein said system comprises a conduit for the flow of the gaseous fuel from the storage tank to the anode of the fuel cell.
