2. DiffuCarb™ E003PT Pt-IrOx Chemically Coated on Platininized Carbon Paper

2.1 Material Properties

• Bimetallic Synergy: The platinum-coated carbon paper provides excellent conductivity and enhanced chemical stability. The Pt-IrOx composite layer not only improves OER catalytic performance but also enhances electron transfer efficiency.
• Enhanced Stability and Durability: The platinum layer acts as a protective barrier, effectively preventing electrode corrosion under extreme conditions, such as high acidity or high temperature, thus extending the electrode’s service life.
• Optimized Ion Transport: The dual-layer structure improves the electrode’s porosity and surface activity, promoting efficient electrolyte penetration and rapid transport of reactants, thereby boosting the overall electrochemical reaction rate.

2.2 Application Fields

• High-Efficiency Water Electrolysis: The Pt-IrOx / platininized carbon paper electrode is particularly suitable for PEM, AEM, and ALK electrolysis systems, showing excellent OER catalytic performance and long-term stability under high current density conditions.
• High-Temperature and Strong Acid Environments: Its exceptional stability and corrosion resistance make this electrode ideal for rigorous industrial water electrolysis applications.

3. Comparison and Summary

3.1 Similarities

• High Catalytic Activity: Both electrode materials contain a Pt and IrOx composite catalytic layer that effectively promotes the oxygen evolution reaction, exhibiting excellent performance in water electrolysis and fuel cells.
• Wide Range of Applications: Both are suitable for PEM, AEM, and ALK electrolysis systems, demonstrating versatility and high efficiency in different electrolyte environments.

3.2 Differences

• Conductivity and Stability: Due to the additional platinum coating, the Pt-IrOx / platinized carbon paper electrode offers higher conductivity and chemical stability, making it particularly suitable for applications under high temperature, high current density, and strongly acidic conditions.
• Cost and Suitability: The Pt-IrOx / carbon paper electrode is more cost-effective and suitable for general water electrolysis and fuel cell applications, whereas the Pt-IrOx / platinum-coated carbon paper, although more expensive, is more advantageous for high-performance and long-life applications.

4. Conclusion

DiffuCarb™ E003 Pt-IrOx Chemically Coated on Carbon Paper and DiffuCarb™ E003PT Pt-IrOx Chemically Coated on Platinized Carbon Paper are highly efficient electrode materials that excel in promoting oxygen evolution reactions in water electrolysis and play a key role in clean energy technologies. Choosing between these electrode materials should be based on the specific application’s requirements for current density, temperature, pH, and cost. The high catalytic performance and stability of these electrodes support more efficient and durable electrolysis devices.
