The excess heat generation of Cold Fusion is determined by the total fusion reaction site on the metal surface and the supply speed of D to the reaction site. In order to increase the reaction site, generally nanoroughness or nano-structure is used on the metal surface, and it is believed that conceptually D supply through the very thin metal film is the best option in the cold fusion community, however, the mechanism is unclear and no available reactor at the engineering stage is not available due to the difficulty to fabricate such thin film structure with sufficient strength and thinness. Thus, I proposed the conceptualized Reactor with the recently developed nano porous metal papers, which has the larger number of the reaction site on the fiber surface, and it is considered to be thin enough and strong enough for Cold fusion metal. The D can be supplied from the back surface and cold fusion is on the front-surface with the proper voltage applied to each counter-electrodes; for D loading counter-electrode is with positive and metal surface potential is negative, and for Cold fusion counterelectrode is with negative for positive metal surface potential. Because this configuration enables the 4He-ash ejection from at the surface T site, and it will improve the performance of cold fusion. Because the nano-porous paper is made of the fiber of nickel, it is semi-transparent, and do not have the capability to block the D2O and H2O. Thus, the nickel metal deposition the backside surface of this nanoporous nickel paper can block the D2O/H2O mixing in the reactor; where H2O is in the Cold Fusion side and D2O is in the D loading side.
