Abstract
In this study, some benzofused tricyclic heterocyclic derivatives have been tested as possible new catalysts for anode hydrazine electrooxidation in a direct hydrazine fuel cell (DHFC). Electrochemical studies were carried out in solution media containing 1 M KOH and 1 M KOH + 0.5 M N2H4 using electrochemical techniques such as cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and chronoamperometry (CA). The CV results obtained showed that 5 catalysts promoted the generation of the best current (38.32 mA/cm2), and EIS results confirmed that an electrode modified with the same derivative presented the lowest charge transfer resistance. All these results proved that 5 organic-based catalysts can be used as an anode-efficient catalyst in hydrazine fuel cells.
