Temperature differences and temperature gradients across Solid Oxide Fuel Cells (SOFCs) are minimized through the used of a manifold heat exchanger (50, 70), which reduces thermal stress and increase cell life. Air passes from a periphery of a cell (54, 74) toward the cell (54, 74) center, where it absorbs cell (54, 74) heat. The air then proceeds to the manifold heat exchanger (50, 70) located adjacent the cell (54, 74), where the air indirectly absorbs further heat. Additionally, fuel is directed countercurrent to air, which keeps hot spots away from cell stack (48) seals and directs hot air toward intense reforming areas on the cell (54, 74) to mitigate quenching effects of internal reforming.
