Abstract

We have applied atomic layer deposition (ALD) processing to deposit ultra-thin platinum layers onto potentially non-precious metals including gold and tungsten as catalysts of fuel cells. The growth of platinum using ALD has been tested on silicon wafers with native oxides and on gold and tungsten. The growth rate was shown to be in good agreement to published values as 0.4Å/cycle. Fuel cell tests are performed by first sputtering porous metal layers onto 200μm-thick 8% yttria stabilized zirconia followed by surface-coating of ALD platinum. We compare the resulting current-voltage curves and maximum power densities with varying temperature.
