DiffuCarb™ E300 IrO2-Carbon Paper (Electrolysis Water Electrode) uses a highly efficient Iridium Oxide (IrO2) catalyst coated on different types of carbon paper substrates, suitable for a variety of electrolysis water systems, including Proton Exchange Membrane (PEM) water electrolysis, Anion Exchange Membrane (AEM) water electrolysis, Alkaline (ALK) water electrolysis, and CO2 Reduction Reaction (CO2RR) anode electrodes. The specific carbon paper substrates selected are F200R raw carbon paper, F200T hydrophobic carbon paper, and F200P platinum-coated carbon paper, with different binders (Nafion or PTFE) used to optimize electrode performance. The details are as follows:

1. Accelerate® Iridium Oxide IrO2 Catalyst

• High Catalytic Activity: IrO2 is a well-recognized catalyst for the Oxygen Evolution Reaction (OER) due to its excellent catalytic performance and corrosion resistance. It can effectively catalyze water splitting reactions at lower voltages, increasing oxygen production rates.
• Corrosion Resistance and Stability: IrO2 has excellent redox stability and corrosion resistance in acidic, alkaline, and neutral conditions, making it suitable for PEM, AEM, and ALK electrolysis technologies.

2. Carbon Paper Substrate and Binder Selection

• F200R Raw Carbon Paper + Nafion Binder:
  • Application: Suitable for PEM, AEM, and ALK water electrolysis.
  • Features: F200R raw carbon paper offers good electrical conductivity and mechanical strength, making it suitable as an electrode substrate. Nafion, as a proton-exchange binder, provides high proton conductivity, helping to improve the overall performance of the electrode and reduce system resistance.
• F200T Hydrophobic Carbon Paper + PTFE Binder:
  • Application: Used in CO2 Reduction Reaction (CO2RR) membrane electrode assemblies (MEA) as the anode electrode, high-temperature electrolysis, and more.
  • Features: F200T hydrophobic carbon paper, treated for hydrophobicity, effectively removes generated gases (like O2) and prevents bubble blockage, maintaining electrode efficiency. PTFE as a binder enhances stability at high temperatures and oxidation potentials, preventing catalyst particle loss and extending the electrode's lifespan. Its hydrophobic properties also improve durability in water electrolysis by preventing excessive oxidation over long operation periods.
• F200P Platinum-Coated Carbon Paper + Nafion Binder:
  • Application: Suitable for PEM, AEM, ALK electrolysis and other water electrolysis systems requiring high ionic conductivity.
  • Features: Platinum-coated carbon paper provides enhanced conductivity and catalytic performance, significantly improving the electrode's overall conductivity and catalytic efficiency. Nafion ensures high proton conductivity and stability, making it highly effective in acidic environments like PEM electrolysis.

3. Characteristics and Advantages

• High Catalytic Efficiency: The combination of IrO2 catalyst with various carbon paper substrates and binders demonstrates highly efficient oxygen evolution catalytic activity, improving electrolysis efficiency at lower voltages.
• Long-Term Stability: When PTFE is used as a binder, the electrode exhibits exceptional stability, particularly in CO2RR MEA anode applications. PTFE enhances the electrode's durability and effectively prevents excessive oxidation of electrode materials, extending its lifespan.
• Versatility: With diverse carbon paper and binder choices, this electrode can meet different electrolysis water technology needs, from the high proton conductivity required for PEM electrolysis to the alkali resistance required for ALK electrolysis, providing excellent performance.
• High-Temperature Operation: With PTFE binder, the electrode can withstand higher operating temperatures without degradation, which is crucial for industrial applications and large-scale hydrogen production systems.

4. Application Prospects

The DiffuCarb™ E300 IrO2-carbon paper (electrolysis water electrode) is flexible in design and offers outstanding performance, capable of meeting the demands of various electrolysis water technologies while also exhibiting broad application prospects in CO2RR and other electrocatalytic reactions. By optimizing the combination of carbon paper substrates and binders, this electrode can further enhance the efficiency and stability of both water electrolysis and CO2RR, providing effective solutions for hydrogen production and carbon capture utilization.
