🌟 DiffuCarb® YLS-30T (X-Series: A, B, C, H) — Enhanced Hydrophobic MPL Carbon Paper

💡 Product Overview

DiffuCarb® YLS-30T (X-Series) is an enhanced hydrophobic microporous layer (MPL) carbon paper based on Toray TGPH060 substrate.
Its layered structure — carbon paper substrate + hydrophobic treatment + MPL coating — is engineered for fuel cells, CO₂ electrolysis, and water electrolysis, ensuring excellent gas–liquid management and long-term electrochemical stability.

🧱 Structure & Material Properties

• Base Material: Toray TGPH060 carbon paper

• Thickness Range: 0.23–0.30 mm (varies with MPL loading)

• Layered Structure: Carbon substrate + PTFE hydrophobic treatment + MPL coating

MPL Material Difference

• A / B / H Series → MPL with Vulcan XC-72R carbon black

• C Series → MPL with Vulcan XC-72 carbon black (granulated version of XC-72R, denser pore structure, suited for high-pressure electrolysis)

🔬 X-Series Classification (X = A, B, C, H)

📌 Key Difference:

• XC-72R → loose structure, higher gas diffusivity → ideal for fuel cells & standard CO₂RR

• XC-72 → granulated, denser pores, reduced porosity → stronger electrolyte blocking in high ΔP systems

📘 Model Definition & Thickness Logic

• Models X2, X3, X4, X5, X6 (X = A, B, C, H) indicate MPL loading level.

• Larger number = thicker MPL layer → stronger hydrophobicity & electrolyte blocking, but reduced gas permeability.

• Smaller number = thinner MPL layer → higher gas diffusion, less flooding resistance.

⚠️ Thickness is not simply “the thicker, the better” — optimal choice depends on application.

• Thin MPL (2–3) → high gas transfer, low resistance, suited for dry fuel cells or low-flooding CO₂RR

• Medium MPL (4) → balanced gas–liquid control, recommended for general electrolysis & R&D

• Thick MPL (5–6) → strong anti-flooding, stable for long-term high-current electrolysis

🧩 Application Scenarios & Recommendations

• CO₂ Electrolysis (CO₂RR) → A3–A4 / C3–C4 (balanced gas diffusion & anti-flooding)

• Fuel Cells (PEMFC / AEMFC) → A2–A3 / H3 (optimized water management & durability)

• Alkaline Water Electrolysis Cathode → B5–B6 / H5–H6 (enhanced anti-flooding & electrolyte resistance)

• Research & Testing → Mix models (e.g., A3 vs. A5) to compare performance under different MPL thicknesses

⚙️ Key Advantages

💧 Adjustable Hydrophobicity — medium to high levels to fit diverse systems
🌬 Superior Gas Diffusion — stable transport, reduced flooding
⚡ High Conductivity — low sheet resistance, supporting high current density
🔧 Mechanical Durability — withstands compression, roll pressing, and hot-pressing for MEA fabrication

🔋 Application Areas

• Fuel Cells (PEMFC, AFC) → as gas diffusion layer (GDL)

• CO₂ Electrolysis (CO₂RR) → as GDE support layer, maintaining triple-phase boundary

• Water Electrolysis (AEM/PEM) → as cathode/anode diffusion layer, reducing electrolyte flooding

• Research & Development → catalyst support, electrode design, hydrophobicity studies

🛠 Handling & Usage Guidelines

• Cutting → laser cutting or sharp blades; avoid fiber breakage

• Stacking → apply uniform pressure to prevent local damage

• Electrolysis → more stable in alkaline environment; in acidic media, short-term use is possible

• Reinforcement → use with titanium/nickel mesh for improved strength & flow management

🎨 Catalyst Coating Workflow

1. Slurry Preparation → mix catalyst powder (e.g., metal nanoparticles on carbon), ionomer (Nafion/AEM), and solvent

2. Dispersion → ultrasonication / stirring for homogeneity

3. Deposition → spray coating, blade coating, or screen printing on MPL surface

4. Drying → 60–80 °C; optional thermal treatment (120–200 °C) for adhesion

5. MEA Fabrication → hot-press with PEM or AEM membranes

❓ FAQ

Q1: Can DiffuCarb® be used as an anode in water electrolysis?
A1: Not recommended — carbon materials degrade at high anodic potentials. Best suited as cathode diffusion layers.

Q2: How to choose between A/B/C/H series?
A2:

• A → moderate hydrophobicity, fuel cells & low flooding risk

• B → higher hydrophobicity, general electrolysis

• C → XC-72 granulated carbon, dense pores, high-pressure environments

• H → highest hydrophobicity, long-term harsh conditions

Q3: Does MPL thickness affect gas diffusion?
A3: Yes — thicker MPL reduces diffusivity but prevents flooding. Balance is required.

Q4: How to maximize lifetime?
A4: Avoid long-term acidic operation; select suitable PTFE/MPL grade; reinforce with metal meshes.

Q5: Is customization available?
A5: Yes — MPL loading, hydrophobicity, and catalyst pre-coating can be tailored.

📘 Product Notes

• Model definition:

  • A2, A3, A4, A5, A6 (and similarly B, C, H series) → the number indicates the MPL loading / thickness level.

  • Higher number → thicker MPL layer, stronger hydrophobicity, higher liquid-blocking effect, but also higher gas diffusion resistance.

  • Lower number → thinner MPL layer, faster gas transport, easier electrolyte penetration.

• Selection guide:

  • Thin MPL (2–3): High gas transfer, low flooding risk (e.g., low-humidity fuel cells, CO₂RR).

  • Medium MPL (4): Balanced, for general electrolyzer and fuel cell use.

  • Thick MPL (5–6): Long-term operation, high current density, or high electrolyte penetration risk (e.g., alkaline electrolysis).

• Applications:

  • CO₂ electrolysis (CO₂RR): A3–A4 / C3–C4

  • PEMFC / AEMFC fuel cells: A2–A3 / H3

  • Alkaline water electrolysis cathode: B5–B6 / H5–H6

  • Research use: compare different MPL thicknesses
