Abstract
A solid oxide fuel cell system including a main plate, an inner cylinder attached to the main plate, an intermediate cylinder attached to the main plate such that the intermediate cylinder contains a cathode air stream, and an outer cylinder attached to the main plate. An exhaust annular gap is formed between the intermediate and outer cylinders such that hot exhaust gases flow through the exhaust annular gap and heat is transferred from the hot exhaust gases to the cathode air stream. The solid oxide fuel cell system may also include a two-stage tail gas combustor.
