Abstract

Direct liquid-feed fuel cells possess high energy and power densities, but suffer from severe adhesion of gas products. Here, a "superaerophobic" surface that enables a small release size and fast evolution behavior of the gas product is introduced, thereby, maximizing and stabilizing the working area. Consequently, the "superaerophobic" nanostructured Cu electrodes exhibit excellent performance as anodes in a direct hydrazine fuel cell.

Keywords: bubble releasing; hydrazine fuel cells; nanostructured Cu films; superaerophobic electrodes.
