POTENTIAL DECAY CURVES FOR ANALYZING THE POLARIZATION BEHAVIOR OF THEGAS-GENERATING ELECTRODE

The electrode process on a gas electrode under nonsteady-state conditi ons (the potential decay curves) is modeled theoretically. Specific fe atures pertaining to the polarization and adsorption characteristics o f the electrode system are revealed for the predominating mechanisms o f recombination and electrochemical desorption. The possibility is dis cussed of elucidating the electrode reaction mechanism at the gas elec trode and the adsorption state at its surface on the basis of an equiv alent electrode capacitance (which includes the double layer capacitan ce and the adsorption faradaic capacitance) and other parameters that characterize the relaxation process after switching off the polarizati on current.
