Abstract

PURPOSE:To surely, accurately detect the amount of hydrogen evolved by simple constitution by immersing a refratometer and a thermometer in an electrolyte and detecting hydrogen evolution based on the measured data. CONSTITUTION:Positive and negative electrolytes 9, 9a are circulated with pumps 26, 26a to make constant current flow to a stack cell 21 and a minicell 27 for charge and discharge. 8-shaped refratometer 1 which detects transmitted light and a thermister thermometer 12 are immersed in the electrolyte 9a in a measuring part 20a and measured data are sent to a microcomputer buit-in signal processor B and the refractive index of the electrolyte is corrected in connection with the temperature of the electrolyte. The same way is applied to the electrolyte 9. The amount of hydrogen evolved corresponding to the imbalanced charging state between positive and negative electrodes is detected based on the refractive index of the electrolytes 9, 9a. By simple constitution, the amount of hydrogen evolved is surely and accurately detected.
