Process for increasing the steam content at the inlet of a fuel steam reformer for a solid oxide fuel cell system with anode recycle

摘要

A process for increasing the steam content at the inlet of a fuel steam reformer for a solid oxide fuel cell (SOFC) stack system without the need for external water addition comprises subjecting the fuel feed, preferably diesel, or the anode gas to a treatment to produce additional water and/or recover the water produced in the SOFC system, optionally doing a fuel reformer recycle by recycling part of the outlet from the fuel reformer to the inlet thereof, and recycling the water or a water-enriched stream to the fuel reformer inlet and/or to a point upstream of the fuel reformer.
