Problems solved by technology

[0004] The size of the CCM membrane and the PET membrane of the membrane electrode are different, and the catalyst coating area has strict requirements on the position of the entire membrane. The conventional method is to cut a single piece of CCM membrane separately and then thermally press it with the PET membrane. This method is inefficient. Difficult positioning and high cost

Abstract

The invention provides a continuous preparation device and method for a membrane electrode, and the method comprises the steps: enabling a CCM material roll to release a CCM membrane under the drivingof a driving roller, conveying the CCM membrane on a conveying belt, carrying out the pre-blanking of the CCM membrane through a CCM membrane pre-blanking machine to remove a redundant part, and conveying the CCM membrane to a PET membrane punching area; respectively arranging a PET material coil and a PET membrane blanking machine above and below the conveying belt, enabling each PET material coil to release a PET membrane under the driving of a driving roller, conveying the PET membrane on the conveying belt, and performing the blanking of the PET membrane by the PET film blanking machine at the corresponding position; and employing a hot press for carrying out overall hot pressing on a three-layer film structure formed by the conveyed CCM film and the conveyed PET film, and then employing an overall blanking machine for carrying out the overall punching on the film structure subjected to hot pressing, so that a final MEA membrane electrode structure is formed. The CCM is pre-blanked, and the blanked CCM membrane and the blanked PET film are subjected to hot pressing and then are integrally blanked, so that the continuity and integrity of the conveying process are ensured, and the efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of membrane electrodes, in particular to a continuous preparation equipment and method for membrane electrodes. Background technique [0002] A fuel cell is a chemical device that directly converts the chemical energy of fuel into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydropower, thermal power and atomic power. Since the fuel cell converts the Gibbs free energy in the chemical energy of the fuel into electrical energy through an electrochemical reaction, it is not limited by the Carnot cycle effect, so the efficiency is high; in addition, the fuel cell uses fuel and oxygen as raw materials; at the same time There are no mechanical transmission parts, so there is no noise pollution, and the emission of harmful gases is very small. It can be seen that from the point of view of saving energy and protecting the ecological environment, ...
