摘要

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.
