▎ 摘　　要

NOVELTY - Schottky diode hydrogen sensor core comprises a four-layer structure and a conductive lead (1). The four-layer structure sequentially includes a hydrogen cracking metal layer (2), a hydroxyl diffusion barrier layer (3), a semiconductor layer (4) and a current collector layer (5). USE - Schottky diode hydrogen sensor core. ADVANTAGE - The Schottky diode hydrogen sensor core has special performance of anti-humidity interference at room temperature, and the water vapor in the gas environment at room temperature will not reduce the sensitivity of the Schottky diode hydrogen sensor core to hydrogen, and reduces humidity of the conventional hydrogen sensor core. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the Schottky diode hydrogen sensor core. (Drawing includes non-English language text).
