摘要： A method and system of fixing carbon dioxide is provided. After metal ion components are extracted from, e.g., natural mineral or steel slag through acid treatment, carbon dioxide is injected to fix carbon dioxide by carbonating the same. Since the procedure of pH adjustment is unnecessary, the reaction is carried out effectively and a continuous process is enabled. Accordingly, the disclosed method of fixing carbon dioxide enables effective removal of carbon dioxide produced from the steelmaking industry, thereby significantly reducing greenhouse gas emission and allowing recycling of the discarded steel slag.

摘要： A rotary pump is provided in which a drive motor is provided such that an output shaft of the drive motor is placed at an offset position, so that a rotational speed of the pump can be changed to a high or low speed. Furthermore, rigid balls or needle roller bearings are used in each rotor unit such that each eccentric rotary body is in rolling contact with a circumferential inner surface of each cylindrical housing, thus reducing friction between them, thereby ensuring smooth rotation of the rotor units. In addition, a space, which is defined between each cylindrical housing and each eccentric rotary body, prevents a cross-plate from being damaged due to torsional stress and tensile force, thereby ensuring superior durability of the pump.

摘要： A method for operating a polymer electrolyte membrane fuel cell at temperatures below the freezing point of water and an apparatus thereof are provided to prevent damage and performance degradation of the membrane-electrode assemblies. Non-humidified gas flows for several seconds before temperature of the polymer electrolyte membrane fuel cell falls below the freezing temperature of water when operation of the polymer electrolyte membrane fuel cell stops. Simultaneously, anode of the polymer electrolyte membrane fuel cell is filled with a solution having a low freezing point to prevent the temperature of a polymer electrolyte membrane fuel cell falling below the freezing point of water due to the lower ambient temperature in the winter. When the polymer electrolyte membrane fuel cell is restarted, the cell performance is not degraded reflecting that the present invention stably preserves the fuel cell.
