✦ Synopsis

Teflon-bonded gas diffusion electrode prepared with different carbon materials for oxygen reduction were investigated with UC impedance spectroscopy and chronoamperometric techniques. Electrodes with different wettabilities showed significant electrochemical characteristics. The mass transport in the electrode with high wettability is dominated by infinite diffusion process; while in the electrode of low wettability, it is characterized by a thin film diffusion.

It is not yet possible to determine in detail the precise micro-structure of porous gas electrodes. It has therefore become customary to analyse actual electrode polarization curve in terms of an electrode model. The degree of cotidence in such analyses is lessened by the fact that certain parameter
