NOVELTY - The steam reformer (100) comprises fluid inlet connections, fluid outlet connections, reforming segments formed by dividing an annular space with segmenting plates extending between an outer surface of an inner cylindrical shell (102) and an inner surface of an outer cylindrical shell (106) and extending longitudinally within the annular space, reforming compartments formed by splitting the reforming segments with a divider plate, a top end plate to seal the first end of the inner and outer shells, a bottom end plate to seal a second end of the inner and outer shells, and a feed manifold.    USE - The steam reformer is useful for production of hydrogen by removing carbon dioxide, where the hydrogen is useful for fuel cell application.    ADVANTAGE - The steam reformer ensures efficient and continuous production of hydrogen with high quality, improved thermal efficiency and increased production rate.    DETAILED DESCRIPTION - The steam reformer (100) comprises fluid inlet connections, fluid outlet connections, reforming segments formed by dividing an annular space with segmenting plates extending between an outer surface of an inner cylindrical shell (102) and an inner surface of an outer cylindrical shell (106) and extending longitudinally within the annular space, reforming compartments formed by splitting the reforming segments with a divider plate, a top end plate to seal the first end of the inner and outer shells, a bottom end plate to seal a second end of the inner and outer shells, a feed manifold connecting a reactant feed to the fluid inlet connections, and a product manifold connecting a product feed to the fluid outlet connections. The reforming compartments are present in fluid communication between the reforming compartments of the reforming segment provided at a first end of the compartment. The bottom end plate comprises the fluid inlet and outlet connections. The reforming segments contain a reforming catalyst and a carbon dioxide adsorbent in a predetermined amount and composition to reform inlet fluids into outlet fluids comprising hydrogen. A cathode off-gas line of a fuel cell is connected to the fluid inlet connections. An anode off-gas line of a fuel cell is connected to the fluid inlet connections. The divider plates extend longitudinally within the reforming segments. The annular space is present in a heat exchange relationship with a space outside the outer cylindrical shell. The reforming segments are present in a heat exchange relationship via the segmenting plates. The reforming compartments are present in a heat exchange relationship via the divider plates. INDEPENDENT CLAIMS are included for:    (1) a method for generating hydrogen; and    (2) a method for forming a steam reformer.
