Abstract

Direct alcohol fuel cells (DAFCs) are a type of electrochemical energy conversion device that directly convert the chemical energy stored in a liquid alcohol fuel, commonly methanol but also ethanol, ethylene glycol, or n-propanol, to electricity. Because of their simplicity, high energy density, instantaneous recharging, and presumably long life, DAFCs have been identified as the most promising candidate to replace batteries in micropower applications. This article presents an overview of DAFC technology, including its working principle, features, challenges, and application opportunities.
