✦ Synopsis

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 + @l x lo-" m2 s-l.

The steady-state reduction ofoxygen in O,-saturated 2 N H,SO, solution was obtalned at constant current on the front side of a Pt fo11 diaphragm before and after strong anodization of the back side. Strong anodization converts the Pt to a Pt-0 alloy. In all cases, the overvoltage for O2 reduction wa
