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 improving the gas quality and quantity at hydrogen filling stations for end users. There are particularly high demands on the hydrogen quality for fuel cell drives. Since impurities are introduced during production, transport, storage and refueling and can be highly critical for the respective functionality, it is sensible to check the purity of hydrogen targeted at different points of the distribution chain. As part of the project, a new measurement 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 about the theoretical analysis of the influence of the process parameters on the Raman signal by inspecting the optical setup to be developed.
