NOVELTY - A hydrocarbon gas is fed into electric reaction technology system to decompose into hydrogen gas and carbon solids. The system has heating zone(s) (120,122,124,126,128) consisting of heating station(s) comprising heating screen(s). After passing the hydrogen gas through the system, hydrogen gas, and remaining carbon solids and hydrocarbon gas are cooled. Hydrogen gas, and remaining carbon solids and hydrocarbon gas are flown through a phase separation system (134) to remove carbon. Hydrogen, carbon solids, and hydrocarbon gas are then flown out.    USE - For producing hydrogen used as heat source for solid oxide fuel cells (claimed).    ADVANTAGE - The method enables efficient and economical production of hydrogen with limited carbon-dioxide emission. The system is designed for minimum residence time to stop free-radical chemical reactions rather than to allow additional time of the gases to approach equilibrium as in the de-carbonization systems.    DETAILED DESCRIPTION - A hydrocarbon gas is fed into an electric reaction technology system to decompose the hydrocarbon gas into hydrogen gas and carbon solids. The electric reaction technology system comprises heating zone(s) (120,122,124,126,128) consisting of heating station(s) comprising heating screen(s). After passing the hydrogen gas through the system, the hydrogen gas, and remaining carbon solids and hydrocarbon gas are cooled. The hydrogen gas, and remaining carbon solids and hydrocarbon gas are flown through a phase separation system (134) to remove all the carbon. The hydrogen, and remaining carbon solids and hydrocarbon gas are flown out of the system. The temperature of hydrogen, and remaining carbon and hydrocarbons leaving the system is 2000-2700degreesF. The hydrocarbon gas feed is heated by the heat generated from the system to 800-1200degreesF. The hydrocarbon is methane. INDEPENDENT CLAIMS are included for the following:    (1) method of utilizing generated carbon as component of molten carbonate fuel cell and product exited from the system as heat source for solid oxide fuel cell;    (2) hydrogen production system; and    (3) pyrolysis method.
