Can Micro-fuel cell sensors be stored in temperatures below freezing?
Although Teledyne does not warrant the extended storage of fuel cell oxygen sensors at temperatures below freezing (zero degrees Celsius), in general it will cause no permanent damage to the sensor to freeze it. At temperatures below zero the sensor will stop working, however, as the aqueous electrolyte will freeze and cease to function. If the sensor is gradually warmed to temperatures above freezing, normal operation typically resumes.
