Purem by Eberspächer targets both mobile and stationary applications with its offerings. Hydrogen recirculation blower for fuel cellsOne of the new developments is the hydrogen recirculation blower (HRB). It is designed to improve hydrogen utilization in the fuel cell stack by recirculating unused hydrogen. The development is based on side channel blower technology and has been adapted to meet the specific requirements of hydrogen. These include increased tightness and optimized materials. Initial field tests with customers are planned for the end of 2025. According to the company, series production is scheduled to begin in 2027.
Modular exhaust system for efficient water managementPurem by Eberspächer is also presenting a modular exhaust system for fuel cells. It consists of several individual components that can be combined into a complete system. The system is designed for efficient water management and compliance with noise emission standards. According to the manufacturer, the water separators are designed for high mass flow rates and offer low back pressure along with high separation efficiency. The silencers are tailored to the requirements of fuel cell vehicles and are resistant to high humidity and water condensation.
Balance of plant: series-production-ready valves for fuel cell systemsIn the area of balance of plant components, Purem by Eberspächer is presenting series-production-ready valve solutions. The gas control valve regulates airflow and pressure in the system and can be used as a bypass or throttle valve. The cathode isolation valve provides hermetic sealing of the cathode path and protects against leakage. Both components are designed for various applications and use suitable materials and customer-specific connections.
In addition, the company is presenting an initial module for direct air capturing at the trade fair. This process is used to extract CO2 directly from ambient air.
Purem by Eberspächer can be found at the Hydrogen Technology World Expo in Hall B6, booth 6F90.
