Chemochromic Hydrogen Detection

Abstract

Hydrogen is becoming an increasingly important fuel source as fossil fuel supplies decline. The low explosive limit of hydrogen makes leak detection a priority when dealing with this fuel. In an effort to support the use of hydrogen, a chemochromic sensor has been developed which is robust, simple to use, and does not require active operation. It can be made into a thin film or tape which can be conveniently used for leak detection at unions, valves, or outlets. There are two forms of the sensor, a reversible and an irreversible, allowing a variety of applications based on individual situations. The irreversible sensor is useful during hazardous operations when personnel cannot be present, while the reversible is ideal for monitoring the status of a leak in person or via a camera. Testing the irreversible sensor against environmental effects has been completed and results indicate this material is suitable for outdoor use in the harsh beachside environment of Kennedy Space Center. The environmental testing has led to increased sensitivity of the irreversible chemochromic sensor. In an effort to advance this technology further, this chemochromic sensor will be integrated into a sensor system using an electrical or optical signal.
