(WO9815023-A1)      An electrochemical fuel cell generator appts. (10) comprises: (a) a generator chamber (28) containing fuel cell bundle(s) (12,14) with electrochemical fuel cells (16), each cell has an exterior fuel electrode (18), an interior air electrode (22), and a solid oxide electrolyte (20) between the electrodes; (b) an oxidant gas inlet (36) connected to the fuel cell interior; (c) a fuel gas inlet (34) connected to the generator chamber and fuel cell exterior; (d) a combustion chamber (30) connected to the generator chamber to burn spent oxidant and gas exiting from the generator chamber; (e) exhaust gas channel(s) (44) connected to the combustion chamber for removing exhaust gas; (f) spent fuel gas recirculation channel(s) (46) connected to the generator chamber to recirculate a portion of the spent fuel gas; (g) reforming chamber(s) (48) including an iron oxide bed, a heater, a fresh hydrocarbon gas inlet (32), and a fuel gas outlet connected to the fuel gas inlet of the generator chamber; (h) a mixing chamber (60) for combining a portion of the spent fuel gas contg. H2O vapour and CO2 with fresh hydrocarbon feed before entering the reforming chamber; (i) reforming catalyst regeneration chamber(s) (50), connected to the fuel gas inlet of the generator, including an Fe bed, a heater, a spent fuel inlet channel to introduce a portion of the spent fuel gas; (j) a control device to switch between the Fe and FeO catalyst beds upon exhaustion of one or the other. Also claimed is a method of conditioning fuel for an electrochemical cell.    USE -   The hydrocarbon gas reformers are used to supply reconditioned fuel for electrochemical fuel cell generators.    ADVANTAGE -   The reformers continuously supply fuel to the generator and the catalyst is continually reactivated. The O species are stored and supplied to the hydrocarbon reformation reaction and the need for additional steam generation is eliminated.
