Product Overview
DiffuCarb® CP-H Series Raw Carbon Paper
DiffuCarb® CP-H Series Raw Carbon Paper is a high-conductivity carbon fiber paper developed for electrochemical applications. Its uniform thickness, stable porous structure, and efficient electron transport make it suitable for fuel cells, electrolyzers, batteries, supercapacitors, and laboratory electrochemical devices.
Standard CP-H products are supplied without PTFE treatment or a microporous layer. PTFE coating and MPL customization are available when a specific level of wettability, gas-liquid management, or catalyst-layer support is required.
3 Standard Models
70–80% Nominal Porosity
0.17–0.25 mm Thickness Range
PTFE / MPL Optional Customization

Key Features
Conductivity, porosity, thickness consistency, and flexible customization
Multiple Thicknesses
Standard thicknesses of 0.17 mm, 0.20 mm, and 0.25 mm support different cell, electrode, and fixture designs.
High Porosity
A porosity range of 70–80% facilitates effective gas and liquid transport through a continuous porous network.
Optional PTFE Treatment
PTFE treatment can be customized to adjust wettability and gas-liquid management for the intended electrochemical system.
Optional Microporous Layer
A customized microporous layer can be added for specific electrode-interface, mass-transfer, or catalyst-support needs.
Stable Carbon Fiber Structure
The carbon fiber paper structure is suitable for research, material evaluation, prototype testing, and industrial development.

Customization and Use
Base model, PTFE treatment, microporous layer, dimensions, and storage
1
Select the Base Model
Choose CP-H170R, CP-H200R, or CP-H250R according to the required assembly thickness and level of structural support.
2
Confirm PTFE Treatment
Standard products are PTFE-free. Specify the required PTFE treatment before ordering when wettability or water management must be adjusted.
3
Confirm Microporous Layer Requirements
Standard products do not include an MPL. Provide the intended application and interface requirements when requesting a customized layer.
4
Select Sheet Dimensions
Choose a listed standard size or request a custom cut. Keep the carbon paper flat and avoid dust, oil, folding, or uneven compression.
5
Storage and Handling
Store unused material in a clean, dry, and sealed environment. Inspect the surface for contamination or visible damage before use.
