ABSTRACT:
A hydrogen sensor includes a solid electrolyte made of a barium cerium oxide, and a first electrode and a second electrode that are formed on the surface of the solid electrolyte. The first and the second electrodes are made of a material having a catalytic effect with respect to an oxidation reaction of hydrogen and are made of the same material. Thus, the hydrogen sensor can be inexpensive and has good hydrogen selectivity and responsiveness to detection, and thus it is possible to measure hydrogen in a high concentration region.
