This series of electrodes utilizes Fueiceel® high surface area platinum black as the catalyst, paired with carbon cloth as the substrate, providing excellent electrochemical activity and durability. Depending on the type of carbon cloth, binder selection, and application, the DiffuCarb™ E224c series electrodes are available in three different models to optimize their performance in different electrolytic environments.

Key Features:

High Surface Area Platinum Black Catalyst:

• The electrode incorporates Fueiceel® high surface area platinum black (Pt Black) as the primary catalytic material. The platinum black catalyst is known for its outstanding electrochemical activity and large surface area, significantly enhancing the efficiency of the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) during water electrolysis. It is particularly suitable for use in various electrolyte environments.

Raw Carbon Cloth Substrate:

• The substrate of the electrode is made from untreated raw carbon cloth, which has not undergone hydrophobic or microporous layer treatments. Although it lacks a hydrophobic layer, this material still provides good conductivity and gas diffusion properties, making it suitable for AEMFC and AFC applications while reducing costs.

• Application: Mainly used in AEM and ALK electrolyzers and their stacks, particularly demonstrating excellent catalytic activity and long-term stability under alkaline conditions.

DiffuCarb™ E224c(T) High Surface Area Platinum Black - Carbon Cloth Electrode (Hydrophobic Type, Water Electrolyzer):

• Substrate: Uses hydrophobic carbon cloth, untreated with microporous layer treatment, with hydrophobic properties aiding in water management.
• Binder: Teflon is used as the binder, ensuring stability and water management functionality in high-temperature environments.
• Application: Suitable for PEM, AEM, and ALK electrolyzers and their stacks, especially effective under high-temperature conditions, ensuring excellent performance during high-temperature electrolysis.

Performance Advantages:

• High Catalytic Activity: The high surface area platinum black catalyst provides a larger active surface area, effectively enhancing the catalytic efficiency during the water electrolysis process.
• Diverse Options: Depending on different electrolyzer types and operating environments, options such as general type, AEM-specific type, and hydrophobic type are available to ensure optimal performance in various applications.
• Excellent Durability: The DiffuCarb™ E224c series electrodes exhibit outstanding mechanical stability and chemical durability in acidic, alkaline, and high-temperature environments, prolonging their lifespan.
• Water Management Capability: The hydrophobic electrode (E224c(T)) effectively manages moisture through the optimized carbon cloth substrate and Teflon binder, enhancing stability in high-temperature and high-humidity environments.

Conclusion:

The DiffuCarb™ E224c High Surface Area Platinum Black - Carbon Cloth Electrode is a multifunctional, efficient electrode that can be widely applied in PEM, AEM, and ALK electrolyzer systems. By optimizing the carbon cloth substrate and binder, it ensures excellent performance in acidic, alkaline, and high-temperature environments, making it an ideal choice for various water electrolyzer systems.
