Paper Abstract

This paper reports on the development, and evaluation, of fiber optic hydrogen sensors based on fiber Bragg gratings (FBG) and an experimental measurement system for long term experiments of fiber optic gas sensors. Two types of palladium metal sensors were manufactured; sputter coated and modified palladium foil with 20 and 100 μm thickness. The responses (at 90 °C with both 1 and 5 % hydrogen) of the coated sensor, the 20 μm and 100 μm foil sensor was found to be 10, 160 and 80 pm respectively to 1 % hydrogen and 25, 480 and 225 pm respectively to 5% hydrogen.
