In order to develop the low-cost and high efficient carbon dioxide capture process which is different from usual thermal adsorption-desorption system, as a basic study, the innovative process with electrochemical reaction was proposed. In this study, the possibility of actual application was evaluated in laboratory scale by measuring and calculating the absorption efficiency, energy cost. And compared other capture system, the effectiveness and the problem of this new process were examined. As the results, it was found that the ohm resistance of electrolyte membrane has to be reduced to one twentieths in order to make the CO_2capture energy less than 1000 kJ/kg-CO_2 .
