Propanol exhibits a substantially higher cell voltage than methanol in a direct liquid fuel cell at a current density less than ca. 100 mA/cm(2). Although the performance increases with cell temperature, the cell can deliver 690 mV at a current density of 20 mA/cm(2) at room temperature. These features could make 2-propanol an attractive fuel for portable power applications. (C) 2002 The Electrochemical Society.
