CeTech Carbon Cloth Sheet (L 100mm * W 100mm * T 0.36mm) for Battery, Electrolyzer, and Fuel Cell, CBEFCCTCCS

CeTech brand carbon cloth (specifically the W0S1011 series) is an industry-standard porous current collector with flexible texture structure. It is woven from continuous carbon fibers (usually PAN-based), giving it high mechanical durability, flexibility, and a high surface area. 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 Carbon Cloth: 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 Carbon Cloth: 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.

The carbon cloth with hydrophilic or hydrophobic surface are suitable as current collector or scaffold for battery, electrolyzer, and fuel cell.
