Abstract:

Fiber optic hydrogen sensing, due to its optical nature, is intrinsically safe and immune to electromagnetic interference, and therefore has become a focus in the research of hydrogen sensors. It is applicable to health monitoring of electric power equipment, hydrogen energy, earthquake monitoring and other fields. This paper reviews the basic principle of four different types of fiber optic hydrogen sensors, and the latest research accomplishments in several types including micro-mirror, interference, evanescent-field, and fiber Bragg grating (FBG). The recent work of the authors' group is introduced in detail. These include palladium alloy fiber optic hydrogen sensor applied to high concentration of hydrogen monitoring, platinum-doped tungsten trioxide fiber optic hydrogen sensor applied to low-medium hydrogen concentration alarm, and tungsten trioxide-palladium-platinum nanocomposite film fiber optic hydrogen sensor applied to ultra-low hydrogen concentration trace monitoring. The state of the above research areas is summarized, and existing problems and prospects of the applications are analyzed.

Key words: hydrogen sensor, tungsten trioxide, fiber optic, palladium alloy, fiber Bragg grating (FBG)
