Abstract

Palladium and its alloys show a high and selective affinity for hydrogen, resulting in a volume expansion. We report on development work using fibre Bragg gratings attached to palladium tubes to monitor strain resulting from hydrogen uptake. The technique is aimed at low concentration hydrogen monitoring where H2 is the result of ageing of polymer materials.
