THE OXYGEN ELECTRODE IN FUSED ELECTROLYTES
Abstract
The Pt/O2 electrode system is evaluated in a molten carbonate electrolyte at 600 - 800 C by the criteria for reference electrodes. This electrode system is found to be stable and reproducible (+ or - 5 mv) and shows a high degree of reversibility by the criteria of bias-potentials, micropolarization, and the Nernst Equation. It is apparent that this electrode system functions as a relative of the metalmetal xide class of reference electrodes. Some results are also reported for gold, rather than platinum, as the metal substrate. While the Au/O2 system satisfies the above criteria for reference electrodes, there is evidence that it equilibrates at/an energy state slightly higher in thermodynamic free energy than the Pt/O2 system.
