| Abstract: | The sol-gel flux phase used in direct methanol fuel cell(DMFC) was prepared by sol-gel method with methyl silicate as the precursor.The discharge performance comparison between the DMFC using sol-gel flux phase and that using liquid flux phase was conducted,the methanol crossover rate through the Nafion117 membrane was determined and the proton conductivity of the sol-gel flux phase was investigated.The results show that the cell performance of DMFC with sol-gel flux phase is a little lower than that of the... |
