DiffuCarb™ E277c Pt Black (High Surface Area) - Carbon Cloth Electrode (W0S1011) for AEMFC is a high-performance electrode specifically designed for anion exchange membrane fuel cells (AEMFC) and alkaline fuel cells. This electrode utilizes untreated raw carbon cloth as the substrate, without hydrophobic or microporous layer treatments, and employs Fumion as the binder, with Fumion coating post-treatment to enhance the electrode's adhesion and chemical stability.

Product Detailed Description:

Carbon Cloth Substrate:

• Untreated Raw Carbon Cloth: The substrate of this electrode is made from untreated carbon cloth that has not undergone hydrophobic or microporous layer treatments, featuring an unmodified surface. The raw carbon cloth provides good conductivity and mechanical strength, maintaining structural stability in the working environments of AEMFC and alkaline fuel cells, and is suitable for operation in alkaline media.

• Substrate Characteristics: The surface roughness of the raw carbon cloth aids in the uniform distribution of the catalyst and binder, ensuring maximization of the electrode reaction area while providing a stable electronic conduction path, enhancing overall performance.

Platinum Black Catalyst Layer:

• High Surface Area Platinum Black: This electrode uses platinum black as the catalyst. The high surface area of platinum black provides numerous active sites, enhancing the efficiency of the oxygen reduction reaction (ORR) and hydrogen oxidation reaction (HOR). This is crucial for both anion exchange membrane fuel cells and alkaline fuel cells, effectively improving the power output and reaction rates of the cells.

• Catalyst Performance: Platinum black can effectively promote electrochemical reactions under alkaline conditions, allowing the electrode to exhibit high electrochemical activity and stability in fuel cells.

Fumion Binder and Coating Post-Treatment:

• Fumion as Binder: Fumion is an alkaline polymer material suitable for AEMFCs, serving as a binder that securely adheres the platinum black catalyst to the carbon cloth substrate. Fumion exhibits excellent chemical stability and durability in alkaline environments, ensuring that the electrode maintains structural integrity under long-term operating conditions.

• Fumion Coating Post-Treatment: During the manufacturing process, Fumion coating post-treatment is applied. This process not only enhances the electrode's adhesion but also optimizes the electrochemical reaction interface, improving ionic conductivity and further enhancing the overall performance of the fuel cell.

Main Application Areas:

• Anion Exchange Membrane Fuel Cells (AEMFC): The DiffuCarb™ E277c electrode demonstrates outstanding performance in AEMFCs, suitable for alkaline working environments. The design of the electrode enhances the efficiency of the oxygen reduction and hydrogen oxidation reactions within the fuel cell.

• Alkaline Fuel Cells: Due to the application of the Fumion binder and the untreated raw carbon cloth substrate, the electrode exhibits good conductivity and water management capabilities in alkaline fuel cells, ensuring stable electrochemical performance during prolonged operation.

Product Advantages:

• Efficient Electrochemical Reactions: The high surface area platinum black catalyst layer provides numerous active sites, significantly enhancing the electrochemical reaction efficiency in both anion exchange membrane fuel cells and alkaline fuel cells.

• Excellent Adhesion and Stability: The Fumion binder and post-treatment coating ensure the structural stability of the electrode and a strong bond between the catalyst and carbon cloth, allowing the electrode to maintain high performance even after extended use.

• Optimized Ionic Conductivity and Water Management: Although the electrode has not undergone hydrophobic and microporous layer treatments, the structure of the raw carbon cloth combined with the Fumion coating effectively manages water conduction and retention, ensuring efficient operation of the fuel cell under various conditions.

Conclusion:

The DiffuCarb™ E277c Platinum Black (High Surface Area) - Carbon Cloth Electrode (W0S1011, AEMFC) is a high-performance electrode designed for AEMFCs and alkaline fuel cells. By utilizing untreated raw carbon cloth as the substrate and Fumion as the binder, the electrode exhibits excellent electrochemical reactivity and stability in alkaline environments, making it particularly suitable for fuel cell systems that require long-term operation.
