DiffuCarb™ E200c Pt on High Surface Area Carbon - Carbon Paper Electrode for Water Electrolysis
Pt / HSC catalyst · A330R raw carbon paper · Nafion binder · AEM / ALK / PEM
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.
The following are its features and advantages:
Platinum-carbon catalyst · A330R raw carbon paper · Nafion binder
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 · ALK Electrolysis · PEM Electrolysis
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.
