One-step electrodeposition of polypyrrole applied as oxygen reduction electrocatalyst in Photoactivated Fuel Cells

This work studies the possibility of using electrodeposited polypyrrole as an oxygen reducing electrocatalyst in photoactivated fuel cells by substitution of the standard Pt/Carbon-Black electrocatalyst. Polypyrrole was deposited on carbon cloth electrodes by one-step electrodeposition that makes construction of a cell fast and easy. Polypyrrole was not a better oxygen-reducing catalyst than Pt/Carbon-Black but in view of the scarcity and the cost of the latter and the rather tedious procedure of fixing Pt/Carbon-Black on a carbon cloth electrode, polypyrrole becomes an interesting alternative.
