Abstract

To achieve accurate detection of hydrogen concentration at the range of under 0.1% to 4% in air, we are developing the quartz resonator hydrogen sensor using platinum catalysts. The platinum electrodes of previous model were fabricated by sputtering. To improve its sensitivity, we focused on the platinum black of which structure has the three-dimensional porous. The electrodes of new model were coated by the platinum black through hydrogen reduction of the hexachloroplatinic acid. From experimental results, it was revealed that the sensitivity of a new model was two times bigger than the previous model.
