Abstract: A fuel cell system includes a solid oxide reversible fuel cell (SORFC) stack that is adapted to generate an exhaust stream containing hydrogen and water vapor from an outlet of the SORFC stack when the SORFC stack is operated in an electrolysis mode, a polymer electrolyte membrane (PEM) hydrogen pump that is adapted to separate at least a portion of the hydrogen contained in the exhaust stream, a first conduit that is adapted to provide the exhaust stream from the outlet of the SORFC stack into an inlet of the PEM hydrogen pump, and a second conduit that is adapted to provide at least a portion of remaining exhaust stream from an outlet of the PEM hydrogen pump into an inlet of the SORFC stack.

Abstract: A computer based records management system comprises an information filter for assuring that record data units offered to the system for storage are complete and not redundant. These record data units may be electronic in nature, scanned from paper, digitally formed from audio, video or otherwise formed as digital data information media, an objective of the disclosed system being to eliminate paper or microform record keeping. If record data units comprising documents are incomplete or redundant, the data units may be queued for special handling, returned or otherwise disposed of. Record data units accepted for system entry are acknowledged and preferably tagged to enable tracking and forwarded for unit verification and certification. Verification and certification includes examination of units for compliance with preset criteria. Once a unit is found to meet the criteria, the unit is stored in permanent storage along with a disposal schedule determined for that unit.
