Abstract
The performance of a direct ethanol fuel cell based on Nafion115 was reported.PtRu/C and Pt/C were used as ethanol anode and oxygen cathode catalysts in a single cell of size 9 cm 2 .The effects of temperature,oxygen pressure,the flow rate of ethanol, and oxygen, and ethanol concentration were tentatively studied.The experimental results showed that the cell open circuit voltage 0.608 V,the cell voltage 0.329 V at 50 mA/cm 2 ,and the peak power density 19.25 mW/cm 2 were reached under the conditions of T cell =85 ℃, P O2 =0.5 MPa, C ethanol =1.0 mol/L and with the flow rate of ethanol and oxygen being 0.5 mL/min and 68 mL/min separately.
