ELECTROCHEMISTRY OF FUEL CELL ELECTRODES. THE ELECTRICAL DOUBLE LAYER ON THALLIUM AMALGAM ELECTRODES,

Abstract

Measurements of double-layer capacity and zerocharge potential were made on 10, 30, and 40% thallium amalgams. These results were compared with existing literature data. The integrated capacity curves agree with litejature values for experimental electrocapillary curves. The surface concentration of thallium, at potentials where overvoltage measurements were made, is one-half to three-fourths of the bulk concentration. In contrast to results reported in the literature, the double-layer capacity of 40% thallium amalgam shows no dependence on frequency, within experimental error in the range from 0.5 kc to 10 kc.
