Beschreibung
Zusammenfassung:	A fuel cell power plant with enhanced water recovery includes a fuel cell power plant adapted to receive a reducing fluid and an oxidant and to generate therefrom electricity and an at least partially saturated exhaust stream; a mass and energy transfer device defining a first flow passage for the wet exhaust stream and a second flow passage for an oxidant stream, the first flow passage being in mass transfer relationship with the second flow passage; and an apparatus for cooling at least one of the oxidant stream, the exhaust stream and the mass and energy transfer device, whereby water is transferred from the exhaust stream to the oxidant stream so as to produce an at least partially saturated oxidant stream. A method is also disclosed.
