At HANNOVER MESSE 2023, Münster-based filtration specialist Hengst will be showcasing various solutions for the safe and efficiency-optimized operation of fuel cells.8 Mar 2023
More than ever, fuel cell systems are expected to play a key role in sustainable energy generation, especially in connection with mobility that is as climate-friendly as possible without harmful emissions. However, practical implementation brings with it challenges - and corresponding potential for optimization. To enable fuel cell stacks to be operated as safely and efficiently as possible, filtration specialist Hengst, for example, offers high-performance solutions that are designed to contribute effectively to the expansion of carbon-neutral mobility, either as modular modules or developed individually for customers.
Hengst is now showcasing three prime examples of such high-performance solutions for the first time at HANNOVER MESSE 2023. The Hengst Blue.iox ion exchanger, for example, is dedicated to the solubility of ionic components in the coolant circuit of fuel cell stacks. The dissolved ions can cause an increase in conductivity, which in turn can result in electrical short-circuit effects as well as power losses of the fuel cell. The Hengst Blue.iox ion exchanger is designed to remedy this situation by always ensuring minimum electrical conductivity of the coolant.
In turn, the use of a cathode filter specially developed for the application is intended to protect the central components of the fuel cell from harmful gases and particles. Particularly effective separation of sulfur gases and ammonia can reliably prevent damage to the fuel cell's catalyst and membrane. Liquid water deposits can also lead to problems. To avoid these and thus ensure permanently effective operation of the fuel cell, proper water management is crucial. Hengst's solution: a new type of separator module for anode gas recirculation. It combines the function of dripping water separation and gas drainage with an innovative valve technology.
