Abstract: The present invention relates to a low-temperature membrane separation device and method for capturing carbon dioxide at a high concentration, in which a gas mixture is passed through a membrane unit to thus separate carbon dioxide. The membrane unit includes a membrane for capturing carbon dioxide and is connected to a feed gas line, a retentate gas line and a permeate gas line. The method includes a first separation step of passing the gas mixture through a first membrane unit and a second separation step of passing the permeation gas, which is discharged to the permeate gas line connected to the first membrane unit, through a second membrane unit. The second separation step is performed at a temperature that is lower than a temperature at which the first separation step is performed.

Abstract: The present invention relates to an electrochemical cell having a channel-type flow-electrode unit.The channel-type flow-electrode structure according to the present invention, which has at least two channel-type flow-electrode units, can significantly reduce manufacturing costs and installation space by reducing the number of parts while extending the electrode capacity to be suitable for large-scale plants for electricity generation, energy storage, desalination, etc. In addition, the channel-type flow-electrode structure can be applied not only to a capacitive flow-electrode device and/or a redox flow battery device, but also to all of the devices for electricity generation, energy storage, and desalination while moving ions or protons.
