A fuel cell unit includes a plurality of angularly spaced fuel cell stacks arranged to form a ring-shaped structure about a central axis, each of the fuel cell stacks having a stacking direction extending parallel to the central axis. The fuel cell unit also includes an annular cathode feed manifold surrounding the fuel cell stacks to deliver a cathode feed flow thereto, a plurality of baffles extending parallel to the central axis, each of the baffles located between an adjacent pair of the fuel cell stacks to direct a cathode feed flow from the annular cathode feed manifold and radially inwardly through the adjacent pair, and an annular cathode exhaust manifold surrounded by the fuel cell stacks to receive a cathode exhaust flow therefrom.
