Abstract
An internally-manifolded solid oxide fuel cell (SOFC) stack is described, including an anode interconnect structure integrated with a cathode interconnect structure. The anode interconnect structure includes a fuel flow field; and the cathode interconnect structure includes an air flow field. The two structures are configured to allow for parallel flow of air and fuel across a plane of the interconnect, while the manifold openings for the fuel are arranged in a cross-flow orientation across a plane of the interconnect structure. Related processes are also described, along with a power generation system that includes an SOFC incorporating this type of interconnect, attached directly or indirectly to at least one power block, such as a combustion engine.
