| Abstract | The mechanism of continuously chlorinated silver-silver chloride electrode performance was studied by using a wiped, rotating, partially submerged, cylindrical silver cathode. The cell performance using a zinc anode was measured, and the rate of chlorination of silver was calculated for several water saturated chlorine atmospheres. At 75°F, with a chlorine partial pressure of 1.00 atm and a rotation speed of 1.36 RPS, a current density of over 100 ma/cm², based on the 13.74 cm² submerged cathode area, was observed when the cathode polarization was 0.19 volts (versus a silver-silver chloride reference electrode). The maximum power density produced was 32 milliwatts/cm² at a current density of 70 ma/cm² under the above operating conditions. The chlorination of silver followed the linear growth equation w = 1.80 x 10⁻⁷ + 6.65 x 10⁻⁷ t, (where w is the weight of chloride formed in g-atoms/cm², and t is exposure time in seconds) during exposures of 0.2 to 2.0 seconds in a 1.00 atm water saturated chlorine atmosphere. At lower chlorine partial pressures, the growth of the chloride film was found to follow logarithmic growth equations of the form w = K₁ + K₂ 1n t. |
