Paper Abstract

The intrinsically safe detection of hydrogen leaks in fuel cell vehicles (FCV) is critical for ensuring system operational safety. An early indication of a leak will not only trigger an alarm in unsafe situations, but will also dramatically reduce the risk and cost associated with fuel cell malfunction. This paper discusses the development of hydrogen leak detection technology that is suitable for onboard, real-time, and intrinsically safe monitoring of fuel cells. This technique offers FCV onboard sensing requirements with a sensitivity of 0.05% (500 ppm) in air, a response time of 3-5 seconds, operation at 5-90%RH and 0-55°C, and power consumption ≤0.5 watts.
