Description

Technical Field

[0001] The utility model relates to the technical field of fuel cells, in particular to a GDL automatic cutting and sorting device. Background Art

[0002] One of the core components of proton exchange membrane fuel cells is the membrane electrode. The membrane electrode is mainly composed of three parts: proton exchange membrane, catalyst layer and diffusion layer. From the perspective of membrane electrode preparation process, the membrane electrode can be divided into gas diffusion layer (GDL) membrane electrode, catalyst coated (CCM) membrane electrode and ordered membrane electrode. The gas diffusion layer (GDL) is a very important component of the proton exchange membrane fuel cell. It is located between the catalyst electrode (CL) and the bipolar plate (BP), including the support layer and the microporous layer. The support layer is usually composed of hydrophobic carbon paper or carbon cloth. It is a key component of the fuel cell and mainly plays the role of mass transfer, electrical conduction, heat transfer, support for the catalyst layer, and water conduction. At the same time, the gas diffusion layer plays the role of diffusing hydrogen / oxygen or methanol / air to the catalyst layer reaction medium, realizing the redistribution of the reaction gas and product water between the flow field and the catalyst layer, which directly affects the performance of the electrode.

[0003] Before the fuel cell unit is packaged, the gas diffusion layer needs to be cut into a specified size to match the specifications of the proton exchange membrane. Therefore, the gas diffusion layer needs to be cut in length and width.
