Increasing thermal dissipation of fuel cell stacks under partial electrical load
First Claim
1. A method of operating a high temperature fuel cell system comprising a plurality of fuel cell stacks, the method comprising operating one or more of the plurality of fuel cell stacks at a first output power while operating another one or more of the plurality of the fuel cell stacks at a second output power different from the first output power.

13. A method of operating a high temperature fuel cell system comprising at least one fuel cell stack, the method comprising:
-
periodically cycling an output power of the at least one fuel cell stack above and below an average desired or required output power, such that the output power substantially equals the average desired or required output power over a period of time;
storing electrical energy when the output power is above the average total desired or required output power; and
releasing the stored electrical energy when the output power is below the average total desired or required output power.
