HYDROGEN SENSOR DETERIORATION DETECTING SYSTEM AND DETERIORATION DETECTING METHOD

摘要

A hydrogen sensor deterioration detecting system comprising a storage device (2) for storing the history of hydrogen measured concentration and measured time measured by a hydrogen sensor (4), and the correlation between the exposure amount and the deterioration amount per specified time of the hydrogen sensor (4), and a control device (3) for determining the exposure amount per specified time of the hydrogen sensor (4) used in the measurement from the history of measured concentration and measured time to determine a deterioration amount from the correlation between the exposure amount and the deterioration amount.
