Multifunctional detection equipment for fuel cell detection

Abstract

The invention discloses multifunctional detection equipment for fuel cell detection, and the multifunctional detection equipment comprises a helium cabin and a buffer cabin; a helium valve is arrangedat the bottom of the helium cabin, a helium inlet valve is arranged on the side face of the helium cabin, a helium source is arranged on the side, away from the helium cabin, of the helium inlet valve, and a clamp is arranged in the buffer cabin; bipolar plates are arranged in the clamps, vacuum valves are arranged on the side faces of the buffer cabins, vacuum pumps are arranged on the sides, away from the buffer cabins, of the vacuum valves, clamp air inlet valves are arranged at the bottoms of the vacuum valves, clamp air outlet valves are arranged at the bottoms of the clamp air inlet valves, and gas detection equipment is arranged at the bottoms of the clamp air outlet valves. According to the multifunctional detection equipment for detecting the fuel cell, by arranging the clamp, the bipolar plate is rapidly sealed by utilizing the clamp, then the leaked gas is detected by the gas detection equipment, the detection steps are optimized, the leakage detection speed is increased, the production efficiency is improved, and rapid batch detection can be realized.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a multifunctional detection device for fuel cell detection. Background technique [0002] A fuel cell is a device that converts hydrogen fuel and oxidant into electrical energy and reaction products. The internal core component of the device is composed of bipolar plates sandwiched by membrane electrodes. During the operation of the fuel cell stack, the bipolar plates perform the following functions to maintain the best working condition and service life of the fuel cell stack: (1) battery conductor , the cathode and anode are formed on both sides of the plate, and the battery cells are connected in series to form a fuel cell stack; (2) provide reaction gas (mass transfer) to the electrode through the flow channel; (3) coordinate the management of water and heat to prevent cooling Leakage of medium and reaction gas; (4) Provide structural strength support to the membrane elec...
