▎ 摘　　要

NOVELTY - The resistor has a resistor material composed of a palladium-graphene composite material and a binder material that is made of epoxy resin, where ratio of the palladium-graphene composite material and the binder material is about 10: 15, and ratio of palladium-graphene oxide and palladium nitrate in the palladium-graphene composite material is about 1: 41. USE - Sensing resistor for detecting hydrogen concentration of a hydrogen sensor (claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing a sensing resistor (2) a hydrogen sensor. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for preparing a sensing resistor.'(Drawing includes non-English language text)'
