Abstract

original image

A micrometer-sized fuel cell based on Nafion/poly(vinyl pyrrolidone) nanowires is presented. The high-performance micro fuel cell containing a single NPNW proved easy to fabricate and delivered reproducible results. Values for the open-circuit voltage, maximum current-density, and power density were orders of magnitude higher than those of traditional fuel cells (see figure). Micro fuel cell assemblies may have future applications in integrated self-powered nanodevices.
