Method and system for producing CO2, purified hydrogen and electricity from a reformed process gas feed using a solid oxide fuel cell. The method having the steps of: introducing the reformed process gas into the solid oxide fuel cell; converting hydrogen and CO of the reformed process gas in combination with oxygen into an anode off-gas including steam, CO2 and unconverted process gas; introducing the anode off-gas into a high temperature water gas shift reactor; in the high temperature water-gas shift reactor, converting CO and steam into CO2 and hydrogen, introducing the gas exiting the high temperature water-gas shift reactor into a low temperature water-gas shift membrane reactor, in the low temperature water-gas shift membrane reactor, converting CO and steam into CO2 and hydrogen, whereby the low temperature water-gas shift membrane reactor comprises a hydrogen pump producing purified hydrogen on a permeate side, while removing hydrogen from a feed side.
