NOVELTY - The method comprises cleaning palladium membrane assembly defect on a surface, preparing repairing palladium film defect detection of solar cell component of a patch material patch comprising palladium or the alloy membrane with a thickness of 5-25 microns and defect size of greater than 3-5 mm, covering the patch, pressing the patch on the palladium membrane component surface defect in a palladium film surface, fastening the patch pressed on the surface of the palladium membrane component arranged with a layer of graphite gasket, and preheating a palladium film hydrogen separator.    USE - The method is useful for repairing palladium film component defect.    ADVANTAGE - The method is capable of simply and rapidly repairing the palladium film component defect without crack in an environmentally friendly manner.    DETAILED DESCRIPTION - The method comprises cleaning palladium membrane assembly defect on a surface, preparing repairing palladium film defect detection of a solar cell component of a patch material comprising palladium or the alloy membrane with a thickness of 5-25 microns and defect size of greater than 3-5 mm, covering the patch, pressing the patch on the palladium membrane component surface defect in a palladium film surface, fastening the patch pressed on the surface of the palladium membrane component arranged with a layer of graphite gasket, preheating a palladium film hydrogen separator and patch surface defect detection of solar cell component for metal diffusion, fastening the patch palladium film component installed in a pressure container, exposing a high voltage side palladium film surface of the palladium membrane component to a pressure vessel and low pressure side of the pressure container, raising the temperature to 250 degrees C using inert gas comprising argon gas and helium gas and pressure in the pressure container under the inert gas environment, rising the temperature speed of less than 5 degrees C/minute, infusing argon gas and hydrogen, argon gas and hydrogen gas to the pressure vessel molar flow of 2-5 using back pressure regulating valve controls, slowly regulating the pressure of 0.1-0.4 MPa, introducing the inert gas to palladium membrane component through a low voltage side pipeline, controlling the pressure in the pressure container, controlling an electric heater to make the pressure container to 650 degrees C, rising the temperature speed of less than 5 degrees C/minute, keeping 650 degrees C for 12-36 hours, stopping heating the pressure vessel begins, when temperature is reduced to 300 degrees C, stopping inletting hydrogen, reducing the temperature to normal temperature, stopping infusing argon gas, opening the pressure container, taking out the palladium membrane component, and obtaining the complete patch of the palladium membrane assembly, flange, a graphite gasket to perform patch palladium membrane component repairing. The graphite gasket is mounted between the patch with the fastener and completely covered by patch with a thickness of 2 mm. The pressure container is adjusted by the electric heater. The patch is replaced by other metal film sheet-palladium.
