Abstract
A potentiometric high concentration hydrogen sensor including a Pd-Pt composite electrode was fabricated by combining a Pt electrode and a Pd nanoparticle layer. The hot-pressing method was used to manufacture a multilayer structure of Pt electrode/Nafion electrolyte/Pt electrode. Pd nanocolloids were synthesized using Pd powder and a solvent, and then coated on the upper Pt electrode to form a Pd nanoparticle layer. The fabricated sensor showed a fast and stable response in the hydrogen concentration range of 70 to 100%, enabling monitoring of hydrogen fuel used in fuel cell vehicles.
