Process and apparatus of CO2 energy source adopted in solid oxide fuel cell - CO2 energy conversion cycle

A process and apparatus of "Solid Oxide Fuel Cell (SOFC)-CO 2 Energy Conversion Cycle (referred to as SOFC-CO 2 -ECC)" are invented to adopt CO 2 as energy sources from waste/stock gas or convert and fix it in the useful compounds.CO 2 is converted into CO and O 2 via simultaneously catalytic and electrochemical reactions in SOFC for power generation and CO 2 cracking. Furthermore, CO is used either as the fuel in SOFC for power generation or starting materials in the chemical reactors to produce CO-derivatives of energy source materials and useful chemical compounds. Hence, SOFC-CO 2 -ECC is an active or scientific carbon cycle with zero emission of CO 2 ., Thus, the efficacy of environmental protection via solving the problem of CO 2 greenhouse effect is achieved, so as to grasp of the "Right of Carbon Emission Trading" issues.
