Hydrogen fuel cell CCM membrane electrode combination or CCM membrane electrode assembly automatic assembling system

Abstract

A hydrogen fuel cell CCM membrane electrode combination or CCM membrane electrode assembly automatic assembling system, comprises a membrane feeding system, an PET membrane feeding system, a positioning cyclic clamp system and a hot pressing system, wherein the PET membrane feeding system places a die-cut first PET membrane on a vacuum suction plate; the membrane feeding system stacks a die-cut CCM membrane electrode at a predetermined position of the first PET membrane; the positioning cyclic clamp system transfers the vacuum suction plate having the first PET membrane and a CCM membrane electrode back to a second station of the positioning cyclic clamp system rightly facing the PET membrane feeding system; the PET membrane feeding system places a second PET membrane with an adhesive facedownward on the CCM membrane electrode; the positioning cyclic clamp system moves a combination formed by the first PET membrane and the second PET membrane into the hot pressing system for hot pressing. The system has the advantages of good lamination consistency, high positioning and alignment precision, low cost and high efficiency.

Description

Technical field [0001] The invention relates to the field of hydrogen fuel cells, in particular to a hydrogen fuel cell CCM membrane electrode assembly or a CCM membrane electrode assembly automatic assembly system. Background technique [0002] Hydrogen fuel cell is a chemical device that directly converts the chemical energy of hydrogen fuel into electrical energy. Because the hydrogen fuel cell converts the Gibbs free energy in the chemical energy of the hydrogen fuel into electric energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so it has high efficiency; in addition, the hydrogen fuel cell uses hydrogen fuel and oxygen As a raw material; at the same time, there are no mechanical transmission parts, so there is no noise pollution, and the discharged water does not pollute the environment. From the perspective of protecting the ecological environment, hydrogen fuel cells are the most promising power generation technology. [0003] Membr...

Problems solved by technology

[0004] In the prior art, methods for preparing CCM membrane electrode assemblies are divided into two categories, one is manual production, and most of them use manual cutting to make sheets, including cutting CCM membrane electrodes, PET membranes and gas diffusion layers (GDL), with the aid of fixtures. Positioning, using a special fixture to position the CCM film electrode and / or PET film, and the gas diffusion layer (GDL), and then use hot pressing to set the shape. This method has the disadvantages of poor staff operation and production consistency, and low positioning and alignment accuracy. High cost, low efficiency and air bubbles in CCM membrane electrode assembly lead to low yield

[0005] After checking the Chinese patent literature, it is found that the Chinese patent literature CN109713343A discloses a continuous preparation equipment and method for membrane electrodes. This roll-to-roll method is stacked and hot-pressed, and there are defects such as low lamination positioning alignment accuracy, and lamination is prone to bubbles and wrinkles.
