Abstract

The influence of high temperature annealing and heavy current treatments of porous Pt electrodes is investigated with scanning electron microscopy. The results are discussed on the basis of the kinetic behaviour of these electrodes, known from the literature or deduced from our still unpublished results.

It is demonstrated that both the structure and the catalytic activity are influenced by the treatments.
