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.

The present invention relates to a hydrogen separation membrane which coats granular ceramic onto the surface of a porous metal support and which coats a hydrogen permeation metal thereon so as to inhibit diffusion between the support and a hydrogen separation layer, and to a method for manufacturing same. As a result, the metal support can be modularized with ease, the hydrogen permeation layer can be made thinner to increase the amount of hydrogen permeation, the use of a separation material can be minimized, and the hydrogen separation membrane can have higher competitiveness.
