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.

A method for sequestrating carbon dioxide in the ocean of the present invention coverts carbon dioxide into a high concentration of bicarbonate ions by using a neutralization method using calcium oxide commonly contained in alkaline industrial waste, prepares elution water for stably containing bicarbonate ions even when making contact with the atmosphere through aeration, and discharges the elution water into an area of the ocean of a relatively shallow depth to sequestrate carbon dioxide. According to the present invention, the present invention is a carbon dioxide storage method which uses alkaline industrial waste to carry out carbon dioxide ocean sequestration at relatively low cost, and can sequestrate carbon dioxide for a long time while minimizing bad environmental influences such as ocean acidification and the like, and is thus environmentally friendly. Therefore, it is possible to actively respond to carbon dioxide emission restrictions and simultaneously achieve economical efficiency by securing certified emission reductions henceforth.

Provided is a high-temperature fuel cell separator. The fuel cell separator includes a fuel gas flow path containing hydrogen, an oxidant gas flow path containing mainly an oxygen component being supplied from an oxygen/nitrogen separator of a system and participating in electrochemical reactions, and a cooling gas flow path containing a nitrogen component to remove heat produced upon power generation of a fuel cell. Such a configuration provides a high-temperature fuel cell separator which is capable of improving efficiency of an overall fuel cell system through improved performance of a fuel cell stack due to increased oxygen partial pressure and which is also capable of improving reliability of the fuel cell stack through inhibition of the occurrence of a high-temperature region resulting from heat produced upon power generation of a fuel cell, by means of a flow of cooling gas containing a nitrogen component.
