DiffuCarb™ E204c Pt Black (High Surface Area) - Carbon Paper (MGL370) Electrode for AEM Fuel Cell

1. Detailed Product Description:

The DiffuCarb™ E204c Pt Black (High Surface Area) - Carbon Paper Electrode (MGL370) is a high-performance electrode designed for use in alkaline fuel cells (AFC) and anion exchange membrane fuel cells (AEMFC). It utilizes Pt black (platinum black) as the catalyst, known for its high electrocatalytic activity and large surface area, which enhances reaction rates for both the hydrogen oxidation reaction (HOR) and the oxygen reduction reaction (ORR). The electrode is built on MGL370 carbon paper, a substrate known for its high conductivity and excellent gas diffusion properties. This substrate has not been treated with PTFE (polytetrafluoroethylene), preserving its high conductivity and ensuring efficient gas transport. Additionally, this electrode can serve as a cathode in alkaline electrolysis water (AEMWE) systems, supporting hydrogen production via water splitting.

2. Features:

• Platinum Black Catalyst: Pt black, a high surface area form of platinum, offers a large number of active sites for electrocatalytic reactions, improving fuel cell efficiency.
• MGL370 Carbon Paper Substrate: A highly conductive and porous carbon paper substrate that supports both efficient electron transport and gas diffusion.
• No PTFE Treatment: The electrode substrate is free of PTFE, retaining high electrical conductivity, which contributes to faster electron flow and improved reaction kinetics.
• Designed for Alkaline Environments: Specifically optimized for AFC and AEMFC applications, the electrode materials are designed to withstand and perform in alkaline conditions.
• Durable and Cost-Effective: The Pt black catalyst and MGL370 carbon paper are chosen to balance performance and durability while keeping costs manageable for commercial applications.

3. Advantages:

• High Catalytic Activity: Pt black offers significantly more active sites compared to conventional catalysts, boosting reaction rates for HOR and ORR, leading to greater fuel cell efficiency.
• Improved Gas Diffusion: The porous nature of the MGL370 carbon paper ensures efficient gas transport, allowing reactants such as hydrogen and oxygen to reach catalytic sites with minimal resistance.
• Superior Conductivity: By avoiding PTFE treatment, the electrode maintains higher electrical conductivity, which is critical for efficient power generation in fuel cells.
• Versatility: The electrode can be used in a variety of systems, including AFC, AEMFC, and alkaline water electrolysis (AEMWE), making it a versatile solution for hydrogen-based energy applications.
• Long-Lasting Performance: The combination of Pt black catalyst and durable carbon paper substrate ensures the electrode can withstand prolonged use in challenging alkaline environments, improving the durability of fuel cells.

4. Applications:

• Alkaline Fuel Cells (AFC): The electrode can be used as a key component in AFC systems, where its high electrocatalytic activity and conductivity enhance the fuel cell’s overall performance.
• Anion Exchange Membrane Fuel Cells (AEMFC): In AEMFC applications, this electrode catalyzes essential reactions efficiently in the alkaline environment, improving energy conversion rates and fuel cell reliability.
• Alkaline Electrolysis Water Cathode (AEMWE): This electrode is also suited for AEMWE systems, acting as a cathode that facilitates hydrogen production via water electrolysis in alkaline conditions.
• Portable and Stationary Power Generation: Ideal for both small-scale portable applications (e.g., backup power systems) and large-scale stationary systems that require efficient, durable fuel cell components.
• Research and Development: Due to its advanced design and high performance, the DiffuCarb™ E204c is also suitable for researchers developing next-generation fuel cells and electrolysis systems.

This electrode’s combination of platinum black catalyst, high-conductivity MGL370 carbon paper, and PTFE-free design makes it a top-tier solution for both alkaline fuel cells and electrolysis systems, offering high efficiency, durability, and versatility across various applications.
