The exhaust technology specialist Purem by Eberspächer has introduced a new exhaust air system for hydrogen-based fuel cell systems. The solution is aimed at both mobile and stationary applications and is intended to enable effective water management and compliance with noise emission requirements.
The system consists of individually combinable modular components. It was developed to specifically discharge the water vapor generated during the reaction of hydrogen and oxygen from the fuel cell system. A central element is the water separators, which are designed for high mass flow rates. They enable low exhaust back pressure and high separation efficiency. This improves the efficiency of the fuel cell stack.
To reduce noise emissions, Purem by Eberspächer has also developed special silencers. These are based on the company’s experience in exhaust technology and are designed for use in intake and exhaust systems of fuel cell vehicles. They are resistant to high humidity and water condensate.
The components of the exhaust air system are individually configured according to customer requirements and the available installation space. The system covers a wide performance range and is suitable for various applications such as long-haul trucks or stationary systems.
In a simulation phase lasting several months, the manufacturer tested the effectiveness of the silencers together with the engineering service provider AVL. The components were integrated into a demo truck and tested on a test bench. According to the company, the tests yielded “excellent results.” Further trials on the test track are planned.
Purem by Eberspächer is a brand of the Eberspächer Group, which specializes in exhaust aftertreatment systems. The company is increasingly transferring its expertise from conventional exhaust technology to applications in the hydrogen and fuel cell sector.
