HyQ²Ra

Research into metrological monitoring of gas quality and mass flow for fuel cell systems

Mobility

The HyQ²Ra project consortium has set itself the goal of ensuring the gas quality and quantity at hydrogen filling stations for the end user. High demands are placed on the hydrogen quality for fuel cell drives. Since impurities are introduced during production, transport, storage and refuelling and can be highly critical for the respective functionality, it makes sense to test the purity of the hydrogen in a targeted manner at various points in the distribution chain.

Within the framework of the project, a new measuring technology based on Raman spectroscopy is being researched and tested for the first time in a 6-month field trial at a hydrogen filling station. The RUB sub-project is concerned with the theoretical analysis of the influence of the process parameters on the Raman signal, taking into account the optical setup to be developed.
