Direct hydrazine fuel cells: A review

Low-temperature fuel cells operating on hydrazine fuel in acid and alkaline media comprise a promising class of new, non-conventional sources of energy. High battery performance is expected of hydrazine-based cells. The electrooxidation of hydrazine on the surface of different catalysts has been extensively studied recently. Examples of Direct Hydrazine Fuel Cells (DHFC) with anion or cation-exchange membranes show notable power densities. These aspects of DHFC development with analysis of future improvements in their performance based on changes such as an increase in catalytic activity, membrane type selection and MEA fabrication, are summarized in the present review.
