Embodiment 1

[0025] A cylindrical self-breathing proton exchange membrane fuel cell, the shape and size of which are the same as those of No. 7, No. 5, No. 2 or No. 1 dry batteries, and can also be made into batteries of larger sizes according to needs. The shape of the battery is cylindrical, including the shell 2, and the membrane electrode 3 is set inside the shell, and the air chamber 4 is between the shell and the membrane electrode. The two ends of the membrane electrode are provided with insulating sealing rings 6 and 9, and the inside of the anode tube is a fuel chamber 11. A threaded sealing cover 1 is set between the cathode output part and the end of the shell. The membrane electrode is composed of cathode, Nafion membrane layer and anode composite. The anode is in contact with the fuel, and the cathode is in contact with the air; the cathode in the membrane electrode is composed of The carbon cloth diffusion layer is composed of a cathode catalyst layer, and the anode is compos...

Description

Technical field: [0001] The invention relates to a proton exchange membrane fuel cell. Background technique: [0002] Proton exchange membrane fuel cell (proton exchange membrane fuel cell, PEMFC) is a low-temperature fuel cell, it uses hydrogen as fuel, air or oxygen as oxidant, is to achieve the use of renewable energy (hydrogen) and zero emissions (its only The emission is water) green energy, is the preferred power source for fuel cell vehicles, and is widely used in civil and national defense fields as a mobile power source. At present, most proton exchange membrane fuel cells are plate-and-frame (flat-plate) structures. In view of the lack of weight and volume of flat-plate fuel cells, researchers have proposed to design PEMFCs with other structures, such as making tubular fuel cells without flow In order to simplify the peripheral equipment of the battery, improve the volume specific power and mass specific power of the battery, reduce the production cost, shorten th...
