A system and method for providing electrical power to an equipment rack using a fuel cell is disclosed. The system discloses: an equipment rack; an electrical device located within the rack; a fuel cell, located within the rack, for generating electrical power; and an electrical bus coupling the electrical power generated by the fuel cell to the electrical device. The method discloses: generating electrical power with a fuel cell located in an equipment rack; transmitting the electrical power from the fuel cell to an electrical device located in the equipment rack over an electrical bus; and adjusting the electrical power generated by the fuel cell in response to electrical power consumed by the electrical device.

What is claimed is: 1. A system for supplying power, comprising: an equipment rack; electrical devices located within the rack; a fuel cell, located within the rack, for generating electrical power; an electrical bus coupling the electrical power generated by the fuel cell to the electrical devices
What is claimed is: 1. A system for supplying power, comprising: an equipment rack; electrical devices located within the rack; a fuel cell, located within the rack, for generating electrical power; an electrical bus coupling the electrical power generated by the fuel cell to the electrical devices; and a fuel cell manager within the rack to: determine an equipment configuration in the rack, the electrical devices being part of the equipment configuration, and adjust an amount of electricity produced by the fuel cell based on the equipment configuration. 2. The system of claim 1: further comprising, a data center, having an electrical bus; wherein the equipment rack is located within the data center; and wherein the electrical bus of the data center is electrically isolated from the electrical bus within the equipment rack. 3. The system of claim 1 wherein the electrical device is a server. 4. The system of claim 1: wherein the fuel cell uses methanol as fuel. 5. The system of claim 1, further comprising: a valve, for varying fuel supplied to the fuel cell, in response to commands from the fuel cell manager. 6. The system of claim 1, further comprising: a communications bus, coupling the fuel cell and the electrical devices to the fuel cell manager, for transmitting data relating to the electrical power generated by the fuel cell and electrical power consumed by the electrical devices to the fuel cell manager. 7. The system of claim 6: wherein the communications bus includes a fiber optic cable. 8. The system of claim 1: wherein the fuel cell is located in a top half of the equipment rack. 9. The system of claim 1: further comprising a battery coupled to the electrical bus, for sourcing and sinking electrical power. 10. The system of claim 1, further comprising a battery electrically connected between the fuel cell and the electrical bus, the electrical power generated by the fuel cell routed through the battery to the electrical bus. 11. The system of claim 5, wherein the fuel cell manager adjusts the amount of electricity produced by the fuel cell by adjusting the valve to control an amount of fuel supplied to the fuel cell, wherein the valve is adjusted according to the equipment configuration. 12. The system of claim 11, further comprising a heater to warm the fuel supplied to the fuel cell. 13. The system of claim 11, wherein the fuel cell manager monitors a voltage of the electrical bus and adjusts the valve in response to the monitored voltage. 14. The system of claim 1, wherein the fuel cell manager analyzes power consumption in the rack and determines a power consumption pattern, the fuel cell manager to adjust an amount of electricity produced by the fuel cell according to the power consumption pattern. 15. The system of claim 1, further comprising a fuel cell manager to enable electrical power to flow from an external electrical grid into the rack in response to determining that the fuel cell is unable to produce more electrical power. 16. The system of claim 1, wherein the equipment configuration includes a number of the electrical devices in the rack and power needs of the electrical devices.
