Multi-specification fuel cell microporous layer intelligent continuous printing equipment and its printing process

Abstract

The invention relates to the field of fuel cells, in particular to an intelligent continuous printing device and a printing process for multi-standard fuel cell microporous layers. It mainly includes multiple screen printing devices, two parallel transmission mechanisms, and a rotary table set between the two transmission mechanisms. The rotary table is equipped with a heating table, a cooling table and a PLC system; this equipment can realize the microporous layer in the Multiple continuous processes of printing-drying-inspection-cooling on one screen printing device solve the problem of large number of ovens and large space occupation, and each screen printing device is connected to the plc system to Realize the independent control of the printing process of each screen printing device, combined with the laser thickness detector, it can timely reprint the same microporous layer according to the printing situation to meet the thickness requirements of the load, or stop printing in time to avoid excess , and the equipment can complete the printing and preparation of at least two gas diffusion layers in one process, and has high working efficiency.

Description

technical field [0001] The invention relates to the field of fuel cells, in particular to an intelligent continuous printing device and a printing process for multi-standard fuel cell microporous layers. Background technique [0002] Proton exchange membrane fuel cell is a power generation device that directly converts chemical energy in fuel and oxidant into electrical energy. It has the advantages of small system volume, high energy density, clean and pollution-free, and does not require complicated air supply and humidification systems. , get the attention of the industry. The membrane electrode is its core component. The membrane electrode is composed of a proton exchange membrane, a catalyst layer and a gas diffusion layer. The gas diffusion layer is an important component of the membrane electrode three-in-one component, and is an important channel for the transmission of reactive gases and generated water. The gas diffusion layer is mainly made of conductive carbon b...
