PtRu / high surface area carbon · A330R carbon paper · Nafion binder · AEM / ALK / PEM
DiffuCarb™ E243c Platinum-Ruthenium Carbon (High Surface Area) - Carbon Paper (Electrolysis Electrode) consists of a high surface area platinum-ruthenium carbon catalyst and an A330R carbon paper substrate, with Nafion used as the catalyst binder. This electrode is suitable for various electrolysis systems, including Anion Exchange Membrane (AEM) water electrolysis, Alkaline (ALK) water electrolysis, and Proton Exchange Membrane (PEM) water electrolysis. For AEM and ALK electrolysis, users can also choose DiffuCarb™ E256c Platinum-Ruthenium/High Surface Area Carbon - Carbon Paper Electrode (MGL370, AEMFC).
Additionally, we have developed the E243a, E243b, and other series, which differ in the type of catalyst used.
The carbon paper substrate is selected from our standard A330R carbon paper, with alternatives available upon request, including Toray (030/060/090/120/050/1.1), AvCarb (MGL190/280/370), CP-H450/H850, and others.

Platinum-ruthenium carbon catalyst · A330R carbon paper · Nafion binder
1. Platinum-Ruthenium Carbon Catalyst
High Surface Area: The platinum-ruthenium carbon catalyst features a high surface area structure, providing more active sites that enhance the efficiency of the water electrolysis reaction. This high surface area allows for higher catalytic activity even at lower voltages, enabling efficient water splitting.
Platinum-Ruthenium Alloy Synergy: The platinum-ruthenium alloy improves the catalyst's oxidation resistance and enhances its catalytic activity for both Oxygen Evolution Reaction (OER) and Hydrogen Evolution Reaction (HER). The introduction of ruthenium reduces the amount of platinum required (lowering costs) and improves the catalyst's overall durability and resistance to poisoning.
2. A330R Carbon Paper Substrate
Conductivity and Mechanical Strength: A330R carbon paper offers excellent conductivity, effectively transmitting current to the catalyst sites, thus minimizing resistance losses. Additionally, its high mechanical strength ensures the electrode maintains structural stability during prolonged electrolysis, resisting damage or deformation.
Hydrophilic Surface: The hydrophilic nature of A330R carbon paper promotes electrolyte penetration and efficient bubble expulsion, which is crucial for improving electrolysis efficiency and maintaining electrode activity.
3. Nafion Binder
Proton Conductivity: Nafion, a polymer membrane material with excellent proton conductivity, not only helps evenly distribute the platinum-ruthenium carbon catalyst but also improves the overall proton conductivity of the electrode. This reduces internal resistance and enhances electrolysis efficiency.
Chemical Stability: Nafion remains chemically stable in acidic, alkaline, and high-potential environments, making it resistant to corrosion. This chemical stability ensures that the electrode can operate efficiently in a variety of electrolysis systems (AEM, ALK, PEM) over the long term.
4. Applicability
AEM water electrolysis · ALK water electrolysis · PEM water electrolysis
AEM Water Electrolysis
In AEM systems, the electrode operates in an alkaline environment. The high activity of the platinum-ruthenium carbon catalyst and the chemical stability of Nafion ensure long-lasting and efficient electrolysis.
ALK Water Electrolysis
For traditional alkaline water electrolysis systems, this electrode effectively catalyzes water splitting reactions. The high efficiency of the platinum-ruthenium alloy catalyst enables the generation of hydrogen and oxygen at lower current densities.
PEM Water Electrolysis
In PEM systems, Nafion, as both a proton exchange membrane and binder, improves proton conductivity and, in synergy with the platinum-ruthenium carbon catalyst, enhances overall electrode performance, making it suitable for efficient hydrogen production.
5. Summary of Advantages
