(US5858314-A)      A reformer (10) comprises a stack of thermally conducting plates (12) interspersed with catalyst plates (14) and internal or external reactant manifolds. As a steam reformer, endothermic steam reforming reaction energy is provided externally to produce carbon monoxide, hydrogen, steam and carbon dioxide.    If used as a partial oxidation reformer, a fraction of the natural gas is oxidised in the presence of a combustion and reforming catalyst in intimate thermal contact with thermally conducting plates elongated in the direction of gas flow. An average in-plane plate temperature is maintained to allow effective reforming action and reduce occurrence of hot spots.    USE -   Provides a compact, plate type, natural gas steam reformer or a partial oxidation reformer using waste heat generated in a closely associated electrochemical converter.
