Abstract
For the measurement of H2 concentrations in the exhaust gas of automotive fuel cells and in its vehicle environment an active diversified-redundant hydrogen gas sensor system will be developed. The combination of a selective metal oxide semiconductor gas sensor and a thermal conductivity detector as well as suitable signal preprocessing enables an application-specific H2 sensor system with high sensitivity, selectivity, stability and safety. Based on updated application specific sensor requirements the work status and current results of the project focused on the current development state of the ambient gas sensor including measurement results will be presented.
