The electrode consists of platinum/high surface area carbon catalyst and carbon paper, using A330R raw carbon paper as the base material and Nafion as the catalyst binder.

In addition, we have developed series such as E200a and E200b, with differences in the catalysts used.

The carbon paper substrate is our standard A330R raw carbon paper, but users can also choose from Toray (030/060/090/120/050/1.1), AvCarb (MGL190/280/370), CP-H450/H850, etc., based on their needs.

This electrode design and configuration can adapt to various types of water electrolysis systems, including Anion Exchange Membrane (AEM) electrolysis, Alkaline (ALK) electrolysis, and Proton Exchange Membrane (PEM) electrolysis. For AEM and ALK electrolysis, users may also choose DiffuCarb™ E203c Platinum/high surface area carbon-carbon paper electrode (MGL370, AEMFC).

The following are its features and advantages:

1. Platinum-Carbon Catalyst

   • High Surface Area: The platinum-carbon catalyst, due to its high surface area, significantly increases catalytic activity, providing a larger reaction interface between the electrode and the electrolyte, thus improving electrolysis efficiency. This catalyst structure helps achieve higher electrolysis rates at relatively lower voltages, reducing energy consumption.
   • Platinum’s High Catalytic Activity: Platinum is a well-known excellent electrocatalyst, particularly suitable for Oxygen Evolution Reaction (OER) and Hydrogen Evolution Reaction (HER) in water electrolysis. Supported by high surface area carbon, platinum particles are more evenly dispersed, enhancing catalytic performance and durability.

2. Carbon Paper Substrate (A330R Raw Carbon Paper)

   • Electrical Conductivity: A330R raw carbon paper has excellent conductivity, ensuring efficient current transmission during the electrochemical reaction and reducing resistance loss.
   • Mechanical Strength and Stability: This carbon paper has good mechanical strength, maintaining its stable structure during electrolysis without deformation or cracking.
   • Hydrophilicity: Raw carbon paper is hydrophilic, facilitating electrolyte penetration and the timely release of gas bubbles, reducing bubble-blocking effects and maintaining active reactions.

3. Nafion Binder

   • Ion Conductivity: Nafion is a commonly used proton exchange membrane material with excellent proton conductivity. As a binder, it helps evenly distribute the catalyst particles and enhances the overall proton conductivity of the electrode, reducing internal resistance.
   • Chemical Corrosion Resistance: Nafion has good chemical stability, remaining stable in highly acidic, alkaline, and high-voltage environments. This allows the electrode to be used in various water electrolysis environments, including both acidic and alkaline electrolytes.

4. Applicability

   • AEM Electrolysis: In AEM systems, the electrode operates in an alkaline environment. The high activity of the platinum-carbon catalyst and the stability of Nafion ensure long-lasting and efficient performance in this environment.
   • ALK Electrolysis: For traditional alkaline water electrolysis systems, platinum-carbon electrodes are also suitable. The electrical conductivity and structural stability of A330R raw carbon paper effectively support large-scale hydrogen production.
   • PEM Electrolysis: In PEM systems, Nafion as the binder matches well with proton exchange membrane materials, ensuring good interface contact between the catalyst and the membrane, enhancing overall efficiency and electrode lifespan.

5. Advantages Summary

   • High Efficiency: High surface area platinum-carbon catalysts provide excellent electrolysis performance, achieving high hydrogen and oxygen output at lower voltages.
   • Versatility: Capable of adapting to various electrolysis technologies (AEM, ALK, PEM), this electrode has wide application potential in electrolysis devices of different scales and conditions.
   • Durability and Stability: With Nafion as the binder and the physical characteristics of A330R raw carbon paper, the electrode maintains stability during long-term operation without significant performance degradation.

Application Prospects
DiffuCarb™ E200c platinum-carbon (high surface area) - carbon paper (water electrolysis electrode) holds significant application potential in the future of green hydrogen production, renewable energy storage, and industrial applications (such as hydrogen supply in chemical production). By optimizing material selection and structural design, its performance can be further improved and costs reduced, driving the commercialization of water electrolysis technology.
