Gas Diffusion Layer
Gas Diffusion Layer are created by various businesses using various techniques. In Mathias et al., the production procedures are described in great depth. 3 If the cell was operated in a way that produced a lot of liquid water, the base material would typically be hydrophilic and all pores would be inundated with water. As a result, water would seal all pores required for gas transmission, rendering the cell inoperable. The Gas Diffusion Layer needs to be treated to develop hydrophobic pores and stop flooding in order to stop these flooding phenomena. In a dip-coating technique, PTFE suspension is typically employed.
