H2 and cation contamination: Aging effects, material and sensor development
Sub-projects: Development and testing of measurement principles for H2 quality monitoring

With this project, ZeMA is continuing its research work in the field of infrared absorption spectroscopy and, together with the project partners, intends to develop a novel measurement system for online hydrogen quality monitoring – an important building block for the reliable use of environmentally friendly hydrogen fuel cells in the transport sector.

problem

Currently, online monitoring of hydrogen quality in petrol stations is not possible. The impurities introduced into the hydrogen through production, transport or storage can cause permanent damage to hydrogen fuel cells and reduce the efficiency of the fuel cell.

objective

As part of the cooperation, an online measuring system, including a multi-channel IR measuring cell with associated electronics, is to be developed for the online quality monitoring of hydrogen or for the detection of contamination, which can be installed directly in the petrol station. In addition, know-how in the field of high-pressure IR spectroscopy and other measuring principles for trace gases will be developed.

approach

Our tasks:

• selection of suitable online measuring methods (IR absorption, if necessary further sensor principles) for the detection of relevant impurities in hydrogen,
• Characterization of hydrogen mixtures at high pressures,
• derivation and implementation of a measurement system,
• design and characterization of a measurement system functional pattern,
• Development of evaluation algorithms,
• Integration into sample filling station with subsequent application tests.
