A system includes one or more positive fuel cell stacks configured to generate a positive portion of an electric potential and one or more negative fuel cell stacks configured to generate a negative portion of the electric potential. The system includes a positive electrical bus bar conductively coupled with the positive fuel cell stacks and configured to conduct the positive portion of the electric potential from the positive fuel cell stacks to one or more loads. The system includes a negative electrical bus bar conductively coupled with the negative fuel cell stacks and configured to conduct the negative portion of the electric potential from the negative fuel cell stacks to the one or more loads. The positive electrical bus bar is elongated and extends between the positive fuel cell stacks and the negative electrical bus bar is elongated and extends between the negative fuel cell stacks.
