Description
Summary:The kinetics of thionyl chloride reduction on porous carbon electrodes consisting of different types of commercial carbon black (including PM 100, PM 100 V, AD 100, activated carbon AG-3, and activated graphitized cloth, with surface areas ranging from 130 to 1600) was investigated. The electrodes were prepared by applying a mixture of carbon material and PTFE (15 percent) to a nickel grid, followed by pressing, drying at 100 C, and sintering under load at 310-325 C. The reduction was carried out at current densities of 0.5-20 mA/sq cm in PTFE cells. Results indicated that current generation occurs mostly in medium size pores. Macropores cease to participate in the reaction quickly, due to the deposition and accumulation therein of solid products. The mechanical properties of cathodes involved in thionyl chloride reduction were also affected by the mechanical properties of the electrode as a whole. (I.S.)
