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.

The present invention provides a bioelectrochemical system for removing a polyvalent ion present in seawater etc., capable of producing electricity. The bioelectrochemical system according to the present invention comprises: an anode chamber comprising an anode which accommodates an electron produced when treating an organic material in wastewater with a microorganism; a cathode chamber comprising a cathode receiving the electron from the anode, for producing a hydroxide ion by reacting the electron with oxygen and water provided from the outside, and depositing the polyvalent ion inside an electrolyte by using the hydroxide ion; and an anion exchange membrane for blocking the polyvalent ion inside the electrolyte from moving to the anode chamber. Also, the present invention provides the bioelectrochemical system capable of removing the polyvalent ion present in seawater etc., and simultaneously producing hydrogen. The present invention comprises: the anode chamber, provided with the anode to which electrochemically active bacteria are attached, for producing the electron by having organic wastewater, as a substrate, injected thereto; the cathode chamber, provided with the cathode, for removing the polyvalent ion and simultaneously producing a hydrogen gas by having seawater, as an electrolyte, injected thereto; the anion exchange membrane for separating the anode chamber and the cathode chamber and preventing the polyvalent cation in seawater from moving to the anode chamber; and a power source connected between the anode and the cathode.

The present invention uses the principles of electrochemical ion absorption (charging) and ion desorption (discharge), and relates to a continuous flow-electrode system, a high-capacity energy storage system, and a water treatment method using the same, in which high-capacity electric energy is stored as electrode materials of a slurry phase and electrolytes simultaneously flow in a successive manner within a fine flow channel structure formed on an electrode. More specifically, the present invention relates to a continuous flow-electrode system, an energy storage system, and a water treatment method, wherein electrode active materials consecutively flow in a slurry state whereby a high capacity is easily obtained without enlarging or stacking electrodes.

The present invention relates to a configuration method of a multifunctional particulate filter (MFPF), capable of reducing the content of particulate material (PM), carbon monoxide (CO) and hydrocarbons (HC), and increasing the content of nitrogen dioxide (NO). The MFPF may coat zeolite and an oxidation catalyst on both exhaust gas intake/discharge sides simultaneously, so as to minimize the slippage of HC and generate high-concentration NO.
