NOVELTY - An electrochemical power system consists of a vessel having one or more cathodes, one or more anodes, one or more bipolar plates, reactants comprising 2 or more components chosen from source of water, source of oxygen, source of catalyst or catalyst, and source of atomic hydrogen or atomic hydrogen, an electrolysis system, and an anode regeneration system. The one or more reactants form source of catalyst, catalyst, source of atomic hydrogen, or atomic hydrogen, and initiate the catalysis of atomic hydrogen.    USE - Electrochemical power system is used in system for generating power in land-based transportation machine e.g. motorcycle, snowmobile, truck, and train, aviation transport machine e.g. turbojet, turbofan, turboprop, turboshaft, propfan, ramjet, and scramjet, marine transport machine e.g. pump-jet, hydro-jet, and water-jet, and work machine e.g. refrigerator, washing machine, dishwasher, lawn mower, snow blower, and brush cutter (all claimed).    ADVANTAGE - The electrochemical power system enables generation of power with solid fuel having high conductivity, reaction rate, and current density.    DETAILED DESCRIPTION - An electrochemical power system consists of a vessel having one or more cathodes, one or more anodes, one or more bipolar plates, reactants comprising 2 or more components chosen from source of water, source of oxygen, source of catalyst or catalyst, and source of atomic hydrogen or atomic hydrogen, an electrolysis system, and an anode regeneration system. The one or more reactants form source of catalyst, catalyst, source of atomic hydrogen, or atomic hydrogen, and initiate the catalysis of atomic hydrogen. The catalyst contains atomic hydrogen (nH, where n is an integer), monoatomic oxygen, dioxygen, hydroxy, hydroxyl ions, or nascent water. INDEPENDENT CLAIMS are included for the following:    (1) water arc plasma power system;    (2) mechanical power system;    (3) power generation system;    (4) generation of power;    (5) ignition chamber;    (6) land-based transportation machine;    (7) marine transportation machine;    (8) aviation transport machine; and    (9) work machine.
