Zusammenfassung:	A hydrogen delivery system for a fuel cell is provided that uses hydrogen as a reactant. A fluid storage vessel contains a hydrogen storage material that reversibly releases and stores hydrogen gas. The released hydrogen gas exits the fluid storage vessel, is pressurized by a fluid pressurization device, and then stored in a ballast vessel. The hydrogen gas is delivered as a reactant to the fuel cell from the ballast vessel at a pressure greater than or equal to the operating pressure of the fuel cell. Variations of the above described hydrogen delivery systems are further disclosed, as well as methods of delivering hydrogen to a fuel cell.
