Methods and systems for providing a portable source of electrical power are disclosed. These methods and systems include portable power supplies and power synchronizing devices. These methods and systems can be used to provide power to residential and commercial buildings, as well as to, for example, emergency equipment, on a temporary basis. The disclosed portable power supply may include fuel cells or batteries as the source of electrical power. When a fuel cell is used, the portable power supply system typically includes a source of hydrocarbon fuel or hydrogen fuel. The portable power supply is preferably mounted upon a moveable platform, such as a truck or trailer, so that it can be transported to the site where needed. The invention is particularly applicable to providing temporary power when fuel-cell type power supply systems, for example, those including PEM-type fuel cell stacks, require servicing. The invention provides temporary power to such fuel-cell systems wherein the power supply to the load is not interrupted.

A method for supplying power to a load powered by an existing power supply, comprising: providing a portable power supply; synchronizing the portable power supply and the existing power supply; powering the load with the portable power supply; shutting down the existing power supply; and servicing the existing power supply. 14. The method of claim 13, further comprising transporting the portable power supply to the load. 15. The method of claim 13 further comprising, after servicing the existing power supply: synchronizing the existing power supply and the portable power supply; powering the load with the existing power supply; and shutting down the portable power supply. 16. The method of claim 13, wherein at least one of the existing power supply and portable power supply includes a fuel cell, the method further comprising introducing one of a hydrocarbon fuel and hydrogen to the fuel cell. 17. The method of claim 16 wherein introducing a hydrocarbon fuel comprises introducing a hydrocarbon fuel selected from the group of fuels consisting of methane, propane, methanol, ethanol, and natural gas. 18. The method of claim 16, wherein the fuel cell comprises a PEM-type fuel cell, and wherein the method further comprises introducing one of a hydrocarbon fuel and hydrogen to the PEM-type fuel cell. 19. The method of claim 13 wherein the existing power supply comprises a fuel cell system including a portable power supply input connector, and wherein the method further comprises connecting the portable power supply to the portable power supply input connector and isolating the existing power supply from the load. 20. The method of claim 13 wherein the existing power supply includes a grid-parallel controller adapted to selectively supply power, the method further comprising selectively supplying power to the load from a utility grid and a fuel cell system using the grid-parallel controller. 21. The method of claim 13, wherein the method further comprises providing an automatic bus-transfer switch and transferring power from the portable power supply to the power synchronizing device using the automatic bus-transfer switch.
