A system includes a fuel cell engine, a plurality of switching devices, and a controller. The fuel cell engine includes a plurality of fuel cell modules connected in series as a fuel cell string, and then a plurality of these strings connected in parallel. The switching device(s) are electrically coupled to bypass when required each module(s) and or disconnect each string(s). The decision whether a module(s) and/or string(s) are bypassed, disconnected, or left to operate is based on a sensory feedback that is input into the finite state machine and fault management process that are embedded within the fuel cell controller. The bypassing scheme at the module level is handled in a manner such that the remaining modules within a series string can provide continuous, uninterrupted flow of current to the end application.
