Effects of NaOH addition on performance of the direct hydrazine fuel cell

Electrochemical oxidation of hydrazine and its derivatives on the surface of metal electrodes in alkaline media

“…In contrast, the oxidation current in the case of the other metal electrodes without hydrazine was insignificant and thus not considered. The electrochemical oxidation of hydrazine in alkaline media can be expressed by the following equation [3,5]:…”

“…Then, a hydrazine fuel cell using a polymer electrolyte was investigated [2][3][4][5]. Hydrazine is one of the most popular reduction agents.…”

Hydrazine electrooxidation on a composite catalyst consisting of nickel and palladium

“…The transfer electron number of the HOR is determined by the N 2 evolution rate at a certain applied current during hydrazine electrooxidation as suggested in our previous work [15]. As shown in Fig.…”

Effects of Pd Nanoparticle Size and Solution Reducer Strength on Pd/C Electrocatalyst Stability in Alkaline Electrolyte

“…1,2 Indeed, this technology allows to use a large panel of fuels instead of pure hydrogen, such as sodium borohydride (and its derivatives, like borane-based chemical compounds) or hydrazine, which reduces the fuel transport and storage issues. Moreover, although platinum and palladium catalysts have already shown interesting performances for DLAFC applications, [8][9][10][11][12][13][14][15] because many complex reactions exhibit faster kinetics in alkaline than in acidic medium, DLAFCs are also compatible with the use of platinum-free catalysts. 16,17 These two advantages reduce the economic impact of the DLAFC technology, as recently demonstrated for direct hydrazine hydrate fuel cells.…”
