💡 Product Introduction
Toray TGPH-F hydrophobic carbon paper is based on Toray TGPH carbon paper substrate, treated with DuPont FEP hydrophobic agent and processed with specific heat treatment.
FEP loading range: 1 wt% – 80 wt% (formula: FEP mass ÷ (FEP mass + carbon paper mass) × 100%).
Standard models: TGPH030F / TGPH060F / TGPH090F / TGPH120F
Hydrophobic treatment significantly improves gas–liquid management performance, effectively preventing electrode flooding, and is widely used in fuel cells, electrolyzers, and electrochemical cells.
✅ Adjustable hydrophobic ratio (1–80 wt%) — flexible to match different operating conditions
✅ Excellent gas–liquid transport — prevents flooding while supporting reactant diffusion
✅ High electrical conductivity — FEP-treated paper maintains conductive pathways
✅ Acid–alkali resistance — suitable for both PEM and AEM environments
✅ High structural stability — withstands stack pressure without pore collapse
✅ Smooth surface — suitable for uniform catalyst layer loading
🚗 Fuel Cells (PEMFC, PAFC): Used as GDL (gas diffusion layer) for improved water management
💧 Water Electrolysis (AEM/PEM): Used as cathode PTL (porous transport layer) to prevent hydrogen electrode flooding
🔋 Battery Current Collector: Lightweight conductive substrate, partially replacing metal meshes or titanium plates
🔬 Research & Development: Used for catalyst support, electrode design, and hydrophobicity studies
(FEP treatment affects porosity and permeability, values vary with hydrophobic ratio)
| Model | Thickness (mm) | Surface Resistance (mΩ·cm) | Gas Permeability | Porosity (%) | Density (g/cm³) |
|---|---|---|---|---|---|
| TGPH-030 | 0.11 | 80 | – | – | – |
| TGPH-060 | 0.19 | 80 | 21 | 23 | 0.44 |
| TGPH-090 | 0.28 | 80 | 21 | 23 | 0.44 |
| TGPH-120 | 0.37 | 80 | 21 | 23 | 0.45 |
✨ Note: Higher FEP content → stronger hydrophobicity, but lower gas permeability. Select according to application.
Storage
Keep in dry, cool, dust-free environment
Avoid long-term exposure to humid air
For long-term storage, vacuum packaging or inert atmosphere recommended
Usage
Cut with sharp blade or laser to avoid fraying
Avoid repeated folding to prevent fiber breakage
Apply uniform pressure when stacking to prevent local damage
In electrolysis, use with titanium/nickel mesh to improve strength and flow distribution
Q1: Can hydrophobic carbon paper be used as anode in water electrolysis?
A1: Not recommended. Carbon materials oxidize under high anode potential; better suited for cathodes.
Q2: How to select hydrophobic ratio?
A2: Low content (1–10%) keeps high porosity; high content (30–80%) enhances flooding resistance. Select based on fuel/electrolyzer conditions.
Q3: Difference from untreated carbon paper?
A3: TGPH-F offers tunable hydrophobicity, providing superior water management.
Q4: Long-term stability in electrolytes?
A4: Stable in alkaline (AEM) environment; in acidic (PEM) can be used short-term but mechanical strength may degrade over time.
Q5: Is customization supported?
A5: Yes, supports customized hydrophobic ratios (1–80 wt%) and different substrates (030F/060F/090F/120F).
In electrochemical energy and water electrolysis systems, carbon paper is often treated with fluoropolymers to enhance gas–liquid management. The two most common hydrophobic agents are PTFE (Polytetrafluoroethylene) and FEP (Fluorinated Ethylene Propylene Copolymer).
Although both belong to the fluoropolymer family, they exhibit distinct characteristics in terms of structure, performance, and application suitability.
| Category | PTFE Hydrophobic Carbon Paper | FEP Hydrophobic Carbon Paper |
|---|---|---|
| Full Name | Polytetrafluoroethylene | Fluorinated Ethylene Propylene Copolymer |
| Structure | Linear polymer, very high molecular weight, high melting point, non-melt-processable | Copolymer structure, lower melting point, melt-processable, more flexible |
| Hydrophobicity | Extremely strong hydrophobicity (contact angle > 110°) | Strong hydrophobicity (contact angle ~105–108°) |
| Coating Adhesion | Moderate adhesion to carbon fibers, requires high-temperature sintering | Stronger adhesion, coating is more uniform and stable |
| Chemical Resistance | Excellent, almost completely resistant to acids and bases | Very good, but slightly lower than PTFE |
| Gas Transport | Strong hydrophobicity blocks liquid intrusion effectively, but may reduce gas diffusivity | Balanced hydrophobicity, allows both liquid blocking and gas diffusion |
| Mechanical Flexibility | Coating tends to be brittle, may crack at higher loadings | More flexible coating, better compressive and bending resistance |
| Cost & Processing | Higher cost, more difficult to process | Lower cost, easier to process and control |
PTFE Hydrophobic Carbon Paper
✅ Advantages: Maximum hydrophobicity, best chemical stability
👉 Suitable for:
PEM fuel cell (cathode GDL)
Systems with very high anti-flooding requirements
Long-term operation in acidic electrolysis environments
FEP Hydrophobic Carbon Paper
✅ Advantages: Strong adhesion, flexible coating, balanced gas–liquid transport
👉 Suitable for:
Alkaline water electrolysis (AEM cathode PTL)
CO₂ electroreduction (CO₂RR)
Research applications requiring both liquid blocking and gas diffusion
If maximum liquid repellence and chemical stability are required → choose PTFE hydrophobic carbon paper.
If balanced hydrophobicity, coating flexibility, and gas transport are needed → choose FEP hydrophobic carbon paper.
Both PTFE and FEP-treated carbon papers have their own strengths; the optimal choice depends on the specific electrochemical application scenario.
