SOFC seal and cell thermal management

摘要

The solid oxide fuel cell (10) module includes a manifold (12), a plate, an electrolyte layer having a cathode electrode on one side and and anode electrode on the opposite side, forming a fuell cell. The manifold includes an air or oxygen (24) inlet in communication with divergent passages above the periphery of the cell which combine to flow the air or oxygen radially or inwardly for reception in the center of the cathode (14) flow field. The latter has interconnects (40) providing circuitous cooling passages in a generally radial outward direction cooling the fuel cell and which interconnects are formed of different thermal conductivity materials for a preferential cooling.
