Design of the pulsed oxygen cathode. 1977

G L Zick

This paper presents a theoretical design of the pulsed oxygen cathode. The analysis concerns two major areas: First, a description of the oxygen diffusion currents during the initial 5 msec. after the application of the polarization potential. Second, a determination of the limiting sample rate imposed by a protective coating of given characteristics. It is shown that at 5 msec. after application of the polarization potential the 99% isoconcentration line is 11.8 micron from the cathode surface. The currents during this time can be modeled as linear diffusion. Also, for a minimum step response of 100 msec. the protective coating should have a thickness less than or equal to 13.6 micron.
