The reduction of oxygen at a metallized membrane electrode

Metallized membrane electrodes have recently been incorporated into analytical devices for monitoring the oxygen content of atmospheres. This paper describes a simple model for this type of electrode structure and shows that it applies well to the conditions used in an analytical device. The diffusion coefficient for oxygen in PTFE is shown to be 1·1 ± 0·1 × 10^?11 m² s^?1.
