230 Microns Thickness Gas Diffusion Layer
HP23
The 230 micron thick gas diffusion layer is an important component in the fuel cell system. Its function is to provide a channel for gas distribution and electron transfer between the cathode and the anode. First, it allows hydrogen to be evenly distributed to the cathode reaction area to ensure uniform reaction. Second, it provides a conductive path so that electrons can flow from the cathode to the anode, thereby forming an electric current. In addition, the gas diffusion layer also has certain wetting properties, which can help maintain a suitable moisture balance and provide the required water vapor transfer.
Quantity
The gas diffusion layer is located on the outer side of CCM and is an important component of MEA. In the reaction and direct contact with the reaction surface, it is necessary to achieve excellent
conductivity, heat resistance, and gas dispersion, which is one of the core components of the battery. Its quality directly affects battery performance.
Thickness, as an important attribute that affects work performance, can serve as a classification standard to showcase different models of products to customers.
