Abstract
For the measurement of H2 concentrations in the exhaust gas of automotive fuel cells and in its vehicle environment the development of an active diversified-redundant hydrogen gas sensor system has been started. 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. Work status and current results of the development will be presented.
