The impinging jet flow cell — a novel method for the study of PEM fuel cell material
The electrocatalytic properties of a fuel cell catalyst ink in thin film form based on Vulcan XC72/Pt (30%) and Nafion was investigated by means of a flow cell of impinging jet type in flows of H 2 and H 2+CO dissolved in H 2SO 4 electrolyte. CO adlayers of different coverages were produced by a dos...

4 electrolyte. CO adlayers of different coverages were produced by a dosing procedure and their electrooxidative removal was studied. Ru was deposited onto the ink in situ by electroreduction and the basic voltammetry of such electrodes was investigated as well as the influence on CO adlayers and CO-tolerance. A Nafion film on top of the ink film influenced both the behaviour of CO adlayers and CO-tolerance. The feasibility of the flow cell for investigation and modification of ink electrodes were demonstrated. |
