The invention discloses a test tool and method for a fuel cell, and relates to the technical field of new energy automobile fuel cell detection. The test tool comprises a bottom pressing plate, a toppressing plate and a guide column located between the bottom pressing plate and the top pressing plate, one end of the guide column slidably penetrates through the top pressing plate, and the upper surface of the top pressing plate is connected with a telescopic piston rod; and sliding holes are machined in the two sides of the top pressing plate and penetrate through the upper surface and the lower surface of the top pressing plate, the sides, away from the center of the top pressing plate, of the sliding holes penetrate through the side wall of the top pressing plate, and a test connector assembly is arranged in each group of sliding holes. The invention further discloses a test method for the fuel cell, interfaces on a fuel cell shell are blocked, any two interfaces of different groupsare connected and ventilated, and air tightness is tested. The tool can be matched with most types and series of fuel cells with shell integrated detection interfaces so that the air tightness of thefuel cells can be conveniently detected, and the purposes of convenience, quickness and high adaptability are achieved.
Description
technical field [0001] The invention relates to the technical field of new energy vehicle fuel cell detection, in particular to a fuel cell testing tool and method. Background technique [0002] Fuel cell testing is generally aimed at testing internal components before leaving the factory, such as testing internal parts such as proton exchange membranes, membrane electrodes, or double-electrode plates, among which airtightness testing is the most critical and complicated. When the fuel cell needs to be returned to the factory for repair, the test for its internal parts often needs to be disassembled before it can be completed, which is time-consuming and laborious. In the existing fuel cells, the detection interface has been integrated into the casing, and only the corresponding test of the external interface is required, which greatly reduces the necessity of disassembly and maintenance. [0003] At present, for the type of fuel cell with an integrated detection interface ...
