Systems and methods include a power module comprising at least one fuel cell generator for powering a load, and a bypass mechanism having a first, normally-open fast-acting switch that closes in 1-250 msec, and a second, normally-open switch in parallel with the first switch, the bypass mechanism being electrically connected between the load and a second power source, such as a grid source, where the first switch is configured to close in response to a fault event such that when the first switch is closed power to the load is provided from the second power source through the first switch, and the second switch closes after a predetermined time such that power to the load from the second source is provided through the second switch. Additional methods and systems include providing power to a plurality of loads using fuel cell power generators.

1. A method of providing power to a plurality of loads, comprising: prioritizing the plurality of loads;connecting the loads to buses based on the load priority;connecting a group of fuel cell power modules to each of the buses to provide a desired redundancy factor for the loads on each bus, wherein the redundancy factor represents a non-zero integer number of fuel cell power modules of the group of fuel cell power modules that may be lost while still meeting a power requirement of the loads connected to each bus;operating the fuel cell power modules to provide power to the loads via the buses;monitoring a load requirement and the power output of the fuel cell power modules for each bus; andin response to determining that the redundancy factor of the loads of a particular bus is increased, redeploying fuel cell modules to the particular bus from another bus based on load priority. 2. The method of claim 1, further comprising: controlling a power output of the fuel cell power modules such that the total power output of the fuel cell power modules connected to each bus is approximately equal to the total load on each bus. 3. The method of claim 1, wherein in response to determining that the load requirement exceeds the power output of the fuel cell power modules on a particular bus, performing at least one of: increasing the fuel cell power module output power;redeploying fuel cell modules to the particular bus from another bus based on load priority;adding stored energy to the particular bus from an energy storage device; andshedding one or more loads from the particular bus based on load priority. 4. The method of claim 1, wherein in response to determining that the power output of the fuel cell power modules exceeds the load requirement on a particular bus, performing at least one of: decreasing the fuel cell power module output power;redeploying one or more fuel cell power modules from the particular bus to another bus based on load priority;charging an energy storage device; andconnecting at least one additional load to the particular bus based on load priority. 5. The method of claim 1, wherein in response to determining that the redundancy factor of the loads on a particular bus is decreased, performing at least one of: redeploying one or more fuel cell power modules from the particular bus to another bus based on load priority; andconnecting at least one additional load to the particular bus based on load priority. 6. A system for providing power to a plurality of loads, comprising: a plurality of fuel cell power modules;a plurality of power buses configured such that one or more loads may be connected to each bus and one or more fuel cell power modules may be connected to each bus to provide output power to the loads; anda controller, coupled to the plurality of fuel cell power modules and the plurality of power buses and having a processor configured with processor-executable instructions to perform operations comprising: prioritizing the plurality of loads;connecting the loads to the plurality of buses based on the load priority;connecting a group of fuel cell power modules to each of the plurality of buses to provide a desired redundancy factor for the loads on each bus, wherein the redundancy factor represents a non-zero integer number of fuel cell power modules of the group of fuel cell power modules that may be lost while still meeting a power requirement of the loads connected to each bus;operating the fuel cell power modules to provide power to the loads via the buses;monitoring a load requirement and power output of the fuel cell power modules for each bus; andin response to determining that the redundancy factor of the loads of a particular bus is increased, the controller redeploys fuel cell modules to the particular bus from another bus based on load priority. 7.
