PTCC NiFe electrolytic catalytic material

In an alkaline electrolysis water hydrogen production environment, an electrocatalyst with high activity and large specific surface area is crucial for promoting the oxygen evolution reaction (OER), enabling efficient operation and reducing energy consumption. Our nickel-iron catalyst meets the requirements of high catalytic activity and low cost, with a single batch production capacity reaching 1 kilogram.

The innovative electrode design combines advanced materials and engineering principles to ensure optimal performance under various operating conditions, without the need for platinum group metals, as these metals are expected to become key resource constraints in the manufacturing of large-scale electrolysis cells.

All electrodes coated with catalysts are based on nickel fibers or nickel foam as the diffusion layer, and coated with cost-effective and abundant non-precious metal materials. These materials are fully suitable for alkaline environments.

Key features

High stability: Designed to maintain outstanding performance during long-term tests.

Excellent performance: With low attenuation rate, it can maintain strong activity under various operating conditions.

Large-scale production process for synthesis: Ensures the consistency and reliability of the product.

Technical specifications

The nickel-iron catalyst is paired with a 50% platinum-carbon catalyst. Under simulated real-world operating conditions, employing the CCS coating technique, both the anode and cathode catalysts exhibit high catalytic activity. The system achieves a performance level of 3.0 A/cm² at 2 V and 60 °C, and 1.72 V yields 1.0 A/cm² at the same temperature. At a current density of 10 mA/cm², the overpotential is as low as 247 mV, indicating a rapid electrochemical reaction rate. The nickel-iron electrode is integrated with an optical network. Using the dual-electrode method, its stability was evaluated in a 1M potassium hydroxide solution over 900 hours, during which the voltage drift rate was measured at 27 μV/h.
