Abstract

The invention discloses a gas tightness testing device for a bipolar plate of a fuel cell in the technical field of fuel cell stack production. The device comprises a machine body, which is internally provided with a mounting plate; a feeding assembly which is connected to the top wall of the mounting plate, and is connected with a lower mold plate through a telescopic assembly, wherein the telescopic assembly is matched with the feeding assembly; and at least three groups of jacking assemblies which are connected to the top wall of the mounting plate, wherein each jacking assembly comprises a pressure applying mechanism and a pressure bearing mechanism, the pressure bearing mechanisms being matched with the lower mold plate. The pressure bearing mechanism comprises a support frame, a pressure-bearing rod and a second elastic piece, wherein the support frame is fixedly connected to the top wall of the mounting plate, and a bipolar plate to be tested is doubly fixed, so that a sealing groove can be perfectly attached to the bipolar plate, the air tightness between the bipolar plate and the upper mold plate and between the bipolar plate and the lower mold plate is ensured, the detection precision and linkage of the device are improved, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of fuel cell stack production, in particular to a device for testing the airtightness of a fuel cell bipolar plate. Background technique [0002] The fuel cell has the advantage of high energy conversion efficiency. It directly converts the chemical energy of the fuel into electrical energy without the combustion process in the middle, so it is not limited by the Carnot cycle. The fuel-to-electricity conversion efficiency of the fuel cell system is between 45% and 60% %, while the efficiency of thermal power and nuclear power is about 30% to 40%, the installation location of fuel cells is flexible, the fuel cell power station occupies a small area, and the construction period is short. The battery is very suitable whether it is used as a centralized power station or a distributed power station, or as an independent power station in a community, factory, or large building, with fast load response and high ope...
