Abstract
A system and method satisfies temperature and pressure requirements of solid oxide fuel cell system 10 in a manner that increases the overall efficiency and decreases the overall weight of system 10. The system and method include a secondary blower 30 for boosting air stream pressure level sufficient for operation of a reformer 12 that is designed to minimize pressure drop; an integrated heat exchanger 18 for recovering heat from exhaust 36 and comprising multiple flow fields 18A, 18B, 18C for ensuring inlet temperature requirements of a solid oxide fuel cell 14 are met; and a thermal enclosure 46 for separating hot zone 48 components from cool zone 50 components for increasing thermal efficiency of the system and better thermal management.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
