    摘要： The present invention relates to a device and a method for detecting a pin hole in a part of a fuel cell stack part to accurately detect the presence of pin holes of stack parts thereby ensuring quality of a fuel cell stack. That is, the present invention provides a system for detecting a pin hole in parts of a fuel cell stack that allows for quality assurance of the fuel cell stack and prevents defective parts from being used, by examining each fuel stack part, which largely influence the quality of the fuel cell stack, using an X-ray device and a vision system, in order to determine the presence of a pin hole in the parts, and a method thereof.

    摘要： The present invention features a pinhole detection system of a fuel cell that preferably includes a stage on which a fuel cell element unit is disposed to be detected, a drive portion that is configured to move the stage so as to rotate the fuel cell element unit, a X-ray source that is disposed at one side of the stage to apply X-ray to the fuel cell element unit that rotates, an image detector that detects X-ray penetrating the fuel cell element unit, and a computer tomography that reconstructs tormogram that is detected by the image detector to a three dimension. Preferably, the fuel cell element unit is rotated on the stage, X-ray is applied to the rotating unit to gain the tomogram thereof, and the tomogram is reconstructed to be a three-dimensional image through a computerized tomography (CT scanning) such that the pinhole formed within the unit can be effectively detected.

    摘要： A system for activating a fuel cell includes a flow meter for measuring the amount of water discharged from an outlet of the air electrode and an outlet of the fuel electrode; a pressure sensor for measuring the pressure at the respective outlets; and a back pressure regulator receiving flow values measured by the flow meters and pressure values measured by the pressure sensors, which are fed back from a controller, and regulating a pressure difference (ΔP=PCathode−PAnode) to be a value greater than 0. With the system, the activation time of a fuel cell and the amount of hydrogen used for the activation can be reduced, thus improving the productivity and manufacturing cost.

    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.
