Abstract
A hidrogen detection system (14) includes a hydrogen sensor(16) that detects contamination within a reaction member and generates a hydrogen contamination signal. A surface spectroscopic system (18) is operational in conjuction with the hydrogen sensor (16) and determines contamination of the hydrogen sensor (16) and generates a sensor contamination signal. A controller (20) is electrically coupled to the hydrogen sensor (16) and the surface spectroscopic system (18) and compares the hydrogen contamination signal to the sensor contamination signal and generates a corrected hydrogen contamination signal.
