ABSTRACT:
In one aspect there is disclosed a method of detecting a hydrogen leak in a fuel cell system that includes the steps of a) providing a hydrogen sensor, b) determining sensor characteristics, c) measuring a hydrogen concentration, d) determining if a hydrogen leak is occurring, and e) performing an action based on the determination of step d). The step of determining the sensor characteristics may include determining an upper detection limit of the hydrogen sensor, as well as determining a minimum time period at the upper detection limit before saturation of the sensor.
