HYDROGEN SENSING METHOD AND APPARATUS USING SOLID ELECTROCHEMICAL TYPE HYDROGEN SENSOR

摘要

The present invention relates to a hydrogen sensing method and a hydrogen sensing apparatus for performing the same. The method comprises the following steps of: heating a solid electrochemical type hydrogen sensor including a solid electrolyte, a sensing electrode, and a reference electrode; detecting at least one characteristic parameter during the heating process; and calculating hydrogen concentration in a measurement environment based on the detected characteristic parameter and a characteristic function of the solid electrochemical type hydrogen sensor. The characteristic function is a function that represents a relationship between the characteristic parameter and the hydrogen concentration. Accordingly, the hydrogen concentration can be rapidly and accurately sensed regardless of a record of the solid electrochemical type hydrogen sensor.;COPYRIGHT KIPO 2020
