PROTON CONDUCTOR ATMOSPHERE DETECTOR

摘要

PURPOSE:To prevent deterioration in a proton conductor, by providing a filter having a basic gas absorbent as effective component to remove a basic gas such as ammonia. CONSTITUTION:In an atmosphere detector using a proton conductor atmosphere sensor, a filter 14 having a basic gas absorbent as effective component is provided. Any filter may be used if it can absorb a basic gas such as ammonia but preferably is the one with a higher ammonium absorption activity by modifying an activated charcoal and an acid salt such as cupric sulfate. This can prevent deterioration by a basic gas such as ammonia thereby enabling the reliability of an atmosphere detector using a proton conductor.
