Toray carbon paper (specifically the TGP-H series) is an industry-standard porous current collector. The choice between hydrophilic and hydrophobic versions depends entirely on how you need your electrolyte and gases to move through the electrode. The primary difference is the presence of Polytetrafluoroethylene (PTFE), commonly known as Teflon.
Hydrophobic Toray Paper: This is "wet-proofed" with PTFE (typically 5% to 30% by weight). The PTFE coats the carbon fibers, preventing liquid water or aqueous electrolytes from soaking into the pores.
Hydrophilic Toray Paper: This version is either untreated (pure carbon) or has undergone a surface treatment (like plasma or chemical oxidation) to make it "wettable." It allows liquids to be drawn into the structure via capillary action.
