novel electrocatalysts for hydrazine fuel cells: enhanced power generation by optimizing bimetallic ni-co nanoparticles on nickel foam (nf)/ reduced graphene oxide as anode and mixed metal oxides as cathode

One of the major challenges in liquid fuel cells is the provision of membrane electrode assembly (mea) electrocatalysts. in the present study, an attempt is made to make a fuel cell with liquid hydrazine fuel without fixing catalytic inks on the nafion. in this regard, the catalytic inks based on ni-co alloy on nf/ rgo is deposited as used anode and the mixture of iridium, tantalum and silisium oxide, mixed metal oxide electrodes (mmo) has been used cathode. the physical characterization of synthesized materials is investigated using fourier transform infrared spectroscopy, scanning electron microscopy, energy-dispersive xray spectroscopy, and x-ray diffraction. maximum power density values of 59 mw cm–2 at 60 °c are obtained for ni50-co50 /rgo. the construction of this type of cells without the use of catalytic inks on nafion has been done for the first time by the electrochemical research team of energy production and storage systems of the faculty of chemistry, university of tabriz.
