Electricity Generation from Decomposition of Hydrogen Peroxide

This paper demonstrates a direct H 2 O 2 fuel cell (DHPFC). The cell converts the energy released by H 2 O 2 decomposition with H + and OH - ions into electricity, and produces water and oxygen. In the experiment, we used amicrofluidic cell, in which acid and alkaline electrolytes contact with each other. The measured power density of the cell is comparable to that of a typical air-breathing direct-methanol fuel cell. The DHPFC emits no CO 2 , uses simply handled aqueous fuels, and requires no expensive membrane-electrolyte assemblies. These advantages may allow the DHPFC to be a promising candidate for practical fuel cells.
