NOVELTY - The composite catalytic sheet-like structure comprises three distinct solid phases, where a first solid phase is comprised of a three-dimensional continuous network of a non-conductive porous ceramic material (CNET), a second solid phase is comprised of electrically conductive fibers (CF) integrated throughout the three-dimensional continuous network of non-conductive porous ceramic material, and a third solid phase is comprised of an effective amount of catalyst particles dispersed throughout the non-conductive porous ceramic material, electrically conductive fibers or both.    USE - The composite sheet-like structure is useful in a catalytic sheet (claimed) that is useful in chemical reactors, in a methanol reformer for producing product hydrogen streams that are useful for a fuel cell stack for producing electrical energy in energy-consuming devices including motor vehicles, recreational vehicles, industrial or construction vehicles, boat or other seacraft, tools, lights or lighting assemblies, a household or other appliance, households, commercial offices or buildings, neighborhoods, an industrial equipment and a signaling or communication equipment.    ADVANTAGE - The composite sheet-like structure exhibits improved rigidity and permeability, and allows economical production of the hydrogen streams with high yield and reaction selectivity.    DETAILED DESCRIPTION - The composite catalytic sheet-like structure comprises three distinct solid phases, where a first solid phase is comprised of a three-dimensional continuous network of a non-conductive porous ceramic material (CNET), a second solid phase is comprised of electrically conductive fibers (CF) integrated throughout the three-dimensional continuous network of non-conductive porous ceramic material, and a third solid phase is comprised of an effective amount of catalyst particles dispersed throughout the non-conductive porous ceramic material, electrically conductive fibers or both. A fourth solid phase is comprised of conductive or non-conductive materials embedded within the first solid phase. The conductive fibers include graphitic fibers. The catalyst is a methanol reforming catalyst. An INDEPENDENT CLAIM is included for a process for producing catalytic sheets.
