Carbon Paper, 210mm*200mm

Carbon Paper is a thin, porous carbon-fiber substrate used as a gas diffusion layer and conductive electrode backing in electrochemical cells. Its fibrous, permeable structure allows reactant and product transport while maintaining electrical contact to the active layer. The sheet format lets the material be cut to the required electrode shape before catalyst deposition or ink coating.

Key Features

• Available in hydrophobic and hydrophilic grades
• Multiple defined grade designations for wettability selection

Specifications

Carbon paper is commonly used in fuel cell and electrolyzer assemblies, gas diffusion electrodes, and general electrocatalysis work, where the choice between hydrophobic and hydrophilic grades controls water management and electrolyte wetting at the electrode. Selecting the appropriate grade helps balance flooding resistance against electrolyte access for a given reaction and cell design.
