A steam reformer with internal hydrogen purification includes internal bulk hydrogen purification, internal hydrogen polishing to remove trace levels of carbon monoxide and carbon dioxide, an integrated combustion method utilizing waste gas to heat the reformer, efficient integration of heat transfer, and a compact design. The steam reformer shown includes a concentric cylindric architecture nesting an annular combustion region, an annular reforming region, an annular hydrogen transport region, and a cylindrical polishing region.
