The invention discloses a quick leak detecting device of fuel cell film electrodes. The quick leak detecting device of the fuel cell film electrodes comprises a quick fastening device and leak detecting dies. The quick fastening device comprises an air cylinder, an upper clamping plate and a lower clamping plate, wherein the upper clamping plate and the lower clamping plate are driven by the air cylinder to be pressed. The multiple leak detecting dies are arranged between the upper clamping plate and the lower clamping plate in a stacked mode. Each leak detecting die comprises a die upper plate and a die lower plate, and after the die upper plate and the die lower plate are pressed in a matched mode, the inside forms a sealed cavity. Film electrodes to be detected are arranged between the die upper plate and the die lower plate, and the sealed cavity between the die upper plate and the die lower plate is separated into a separate upper cavity and a separate lower cavity. An air inlet is formed in the side wall of the die lower plate, an air outlet is formed in the side wall of the die upper plate, and the air outlet is connected with an airtightness leak detecting instrument. The quick leak detecting device of the fuel cell film electrodes can detect gas permeability of multiple film electrodes at one time, and the detecting speed is higher when the air cylinder drives the leak detecting dies to be fastened together.
Description
technical field [0001] The invention relates to a fuel cell membrane electrode leak detection device, in particular to a fuel cell membrane electrode fast leak detection device with a fast fastening device. Background technique [0002] Polymer Electrolyte Membrane Fuel Cell (PEMFC) technology is the most efficient means of utilizing hydrogen energy. Polymer electrolyte membrane fuel cell is a device that directly converts the chemical energy of hydrogen into electrical energy. It has the advantages of high efficiency, low noise, and zero pollution, and is playing an increasingly important role in today's society. Polymer electrolyte membrane fuel cells usually need to assemble multiple single cells in series into a stack. The main components include bipolar plates, membrane electrodes (MEA), end plates and fasteners, among which bipolar plates and The gas leakage of membrane electrodes determines the performance and life of polymer electrolyte membrane fuel cell stacks.
