Direct fuel cells such as those fed with ethanol (DEFCs) that employ anion exchange membranes can use non-platinum catalysts, which greatly reduces their system costs. In this study, we describe a passive air-breathing monoplanar alkaline DEFC equipped with a nanostructured carbon-supported anode (Pd) and cathode (FeCo) electrocatalysts. This DEFC was able to supply up to 30 mW cmâ2of peak electrical power density and was able to provide an almost constant amount of power at 1 mA cmâ2load for 3 months at room temperature. After such long periods of functioning at constant load, no degradation (physical or electrochemical) of the Pd-based anode catalyst was observed.
