WebGas diffusion layers can be treated with extra Microporous layers and PTFE. The main properties of Carbon GDLs containing PTFE and MPL are that they improve water transport and management. Because water retention reduces power generation, GDL treated with PTFE (Teflon) can make the material hydrophobic and improve water transport.
WebThe GDE experiments were conducted based on the previous reports. 39,40 The hydrophobic gas-diffusion layer (GDL) was prepared from a mixture of 70 wt% carbon black (TOKAI CARBON, #3800) and 30 wt% polytetrafluoroethylene (PTFE). The resultant carbon/PTFE mixture was rolled in several steps to obtain 0.3 mm-thin sheets. WebJun 27, 2024 · The prepn. conditions of the gas diffusion electrode were optimized by adjusting the amts. of polytetrafluoroethylene (PTFE) in the gas diffusion layer and acetylene black in the catalytic layer.
