EWIN TECH HC100: Innovative gas-solid-liquid three-phase boundary technology, breaking through the traditional RDE dissolved oxygen mass transfer bottleneck; Can precisely simulate the MEA conditions.

The EWIN TECH HC-100 Redox Catalyst Test Fixture is designed to overcome the limitations of traditional Rotating Disk Electrode (RDE) testing. This series of fixtures was proposed by Toyota. It innovatively adopts the three-phase boundary technology of gas-solid-liquid, directly constructing an efficient mass transfer channel for oxygen diffusion layer to the catalyst surface. The fixture solves the limiting current density limit caused by the dependence of traditional RDE on dissolved oxygen ( traditionally only ~ 6 mA/cm² ). The measured current density is significantly enhanced, closely aligning with real membrane electrode (MEA) conditions. Through the precise control of multi-parameters such as oxygen flow rate and electrolyte concentration, the influencing factors of catalyst activity can be deeply analyzed. Combined with the highly simulated MEA structure and micro-area test design, the whole chain performance evaluation from catalyst development to process matching can be realized. The system adopts PEEK + 316L + PFA acid-resistant material, which is suitable for 0.5 cm² micro-area test. It has both compactness and high corrosion resistance. It provides a high-precision and high-reliability one-stop solution for fuel cell catalyst research and development, working condition simulation and industrial application.
