This work reports on recent advances in the development and characterization of a miniaturized hydrogen sensor system based on the combination of an yttria-stabilized zirconia (YSZ) solid electrolyte coulometric (SEC) detector and a gas chromatographic (GC) separation process. A commercial oxygen-pumping cell was characterized for its sensitivity, long-term stability and accuracy under different operational conditions. The resulting insights were used to define appropriate boundary conditions and construction guidelines for miniaturizing different components such as the sample injection system, the GC column heating/cooling module and the SEC detector.
