Abstract

PURPOSE: To detect the degree of cathode deteriotation by using a platinum-based catalyst to burn hydrogen generated from deteriotated oxygen-reducing cathode and measuring temperature increase due to combustion heat.
CONSTITUTION: The electrolytic tank 1 is partitioned by a cation-exchange membrane 2 into anode chamber 4 having anode 3 and cathode chamber 5, the cathode chamber 5 is further partitioned by oxygen-reducing cathode 6 to provide an oxygen gas (air) supply chamber 7. Aqueous alkali chloride solution is guided from an inlet 8 and dilute brine is discharged from an outlet 9. Water is supplied from a water- port 10 into the cathode chamber 5 and produced caustic alkali solution is discharged from an outlet 11. Meanwhile, oxygen or air is supplied from an inlet 12 and flowed out of an outlet 13. Hydrogen generated at cathode deterioration time is separated in gas-liquid separator 14 above the outlet 11 and is guided in catalyst- filled layer heated to a specified temperature, while air is passed through the reaction tube 15 filled with catalyst, and the temperature rise due to combustion heat is measured with a thermometer 16.
