ABSTRACT:
An apparatus for powering a unipolar motor may include a solid oxide fuel cell having a plurality of sub-modules, a unipolar generator having a plurality of armature turns, and a plurality of jumpers. Each of the sub-modules may produce fuel cell electric power at the fuel cell terminals. Each of the armature turns may produce generator electric power at the generator terminals. The jumpers may interconnect the fuel cell terminals with the generator terminals in order to provide a configurable voltage-current profile for the unipolar motor. The fuel cell may have a fuel cell housing and the generator may have a generator housing. The fuel cell terminals may be located outside of the fuel cell housing and the generator terminals may be located outside of the generator housing. Each of the sub-modules and each of the armature turns may produce a voltage. The jumpers may interconnect the fuel cell terminals in series with the generator terminals in order to sum the voltages for the unipolar motor. Alternatively, the sub-modules may be equal in number to the armature turns and each of the sub-modules may be connected in series with a corresponding one of the armature turns in order to directly provide power to the unipolar motor.
