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 30mWcm(-2) of peak electrical power density and was able to provide an almost constant amount of power at 1mAcm(-2) load for 3months 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.
