Fuel cell or a partial oxidation reactor or a heat engine and an oxygen-enriching device and method therefor

A combined cycle system, comprising:

• a top stage including a partial oxidation reactor that has oxygen as one of its reactants, and which produces heat as one of its reaction by-product outputs;
• and
• a bottom stage including a non-cryogenic oxygen-enriching means coupled to said top stage, said bottom stage receiving said heat by-product output of said partial oxidation reactor of said top stage, said heat by-product output being consumed by said bottom stage to produce an oxygen-enriched gas mixture output that is fed to said partial oxidation reactor of said top stage as a reactant input for said partial oxidation reactor of said top stage for reactive use therein.
