Abstract: A method includes providing steam to the solid oxide fuel cell stack, splitting exhaust gas from the cell stack into two portions, a first portion directed to a superheater and a second portion directed to an ejector and to a hydrogen separator. At least part of the first portion of the exhaust gas that is directed to the superheater is subsequently boiled in a boiler and then returned to the superheater. After being returned to the superheater, this part is directed to the ejector as high pressure steam so as to drive the ejector.
