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 · corrosion resistance · substrate and binder selection
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.
