1. A method of operating a modular fuel cell system, comprising: providing a system comprising a plurality of fuel cell stack modules, at least one fuel processing module, and at least one power conditioning module, wherein each of the plurality of fuel cell stack modules comprises one or more fuel
1. A method of operating a modular fuel cell system, comprising: providing a system comprising a plurality of fuel cell stack modules, at least one fuel processing module, and at least one power conditioning module, wherein each of the plurality of fuel cell stack modules comprises one or more fuel cell stacks located inside a cover dome comprising thermally insulating material, and at least one of the plurality of fuel cell stack modules is located inside a hot box container and the hot box container comprises at least one door, and the hot box container is separate from the cover dome; andtaking at least one fuel cell stack module off line without taking the remaining fuel cell modules, the at least one fuel processing module and the at least one power conditioning module off line, comprising: accessing the cover dome in which the at least one fuel cell stack module is located by opening the at least one door of the hot box container;accessing the at least one fuel cell stack by at least one of removing the cover dome from a base having a surface which supports the fuel cell stack module, opening a door in the cover dome, or opening a hatch in the cover dome; andstopping a flow of fuel through a first fuel inlet line to the at least one fuel cell stack module using a valve while the fuel continues to flow to the remaining modules through fuel inlet lines other than the first fuel inlet line;wherein each type of module is installed in or on a separate container; andthe containers are located separately from each other. 2. The method of claim 1, wherein the step of taking at least one module off line comprises servicing, repairing or removing the at least one module from the system without servicing, repairing or removing the remaining modules. 3. The method of claim 1, wherein: the system contains a plurality of each type of module; andwhen at least one module is taken off line, the remaining modules of the same type are not taken off line. 4. The method of claim 1, wherein the at least one fuel processing module processes at least one of the following fuels selected from natural gas from a pipeline, compressed natural gas, propane, liquid petroleum gas, gasoline, diesel, home heating oil, kerosene, JP-5, JP-8, aviation fuel, hydrogen, ammonia, ethanol, methanol, syn-gas, bio-gas, and bio-diesel. 5. The method of claim 1, wherein stopping a flow of fuel comprises turning the valve off manually. 6. The method of claim 1, wherein stopping a flow of fuel comprises turning the valve off electronically. 7. The method of claim 1, wherein taking at least one fuel cell stack module off line further comprises electrically disconnecting the at least one fuel cell stack module. 8. The method of claim 1, wherein the at least one fuel processing module comprises a desulfurizer material for a natural gas fuel.
