Abstract

Direct ethylene glycol fuel cells, in which the oxidation of ethylene glycol and the reduction of oxygen take place at the anode and the cathode, respectively, are promising candidates as electric power sources of portable devices such as the cellular phone and the laptop computer. The advantages of ethylene glycol are high activity, high energy density, low volatility, and high boiling point compared with other organic fuels such as methanol and ethanol. In this article, the construction of direct ethylene glycol fuel cells, the electrooxidation of ethylene glycol in acid and alkaline solutions, cathode catalysts, and operating conditions such as temperature, pH of the electrolytes, and the concentration of ethylene glycol are described.
