| 英文摘要 | in the present work, nafion (r) membrane porosity changes were determined in aqueous ethanol solutions with different concentrations by weighing vacuum-dried and ethanol aqueous solution equilibrated membranes at room temperature. the ethanol crossover rate through nafion (r)-115 membrane at different temperatures and different concentrations had been investigated in a fuel cell test apparatus by using membrane gets higher as ethanol solution gas chromatography analysis. the experimental results show that the swelling degree of nafion (r) concentration increases. the ethanol crossover rate increases with ethanol concentration and temperature increment. the single direct ethanol fuel cell (defc) tests were carried out to investigate the effect of ethanol concentration on ethanol crossover and consequently, on the open circuit voltage and the cell performance of defc. it can be found that ethanol crossover presented a negative effect on the ocv and the cell performance of defc. it can also be found that an improved defc performance was obtained as temperature increased although the ethanol crossover rate increased with temperature increment.
