چکیده انگلیسی
The performance of direct fuel cells using dimethyl ether(DME)-based fuels is presented at a relatively low temperature of 80 °C. DME is supplied to the fuel cells either by gas phase or aqueous phase for the operation of direct fuel cells. In order to keep DME in liquid phase during operation, fuel cells were operated at higher pressure up to 5 bar. For further increase of the power density from direct DME fuel cells, DME was mixed with methanol solution and fed into the fuel cells by the vapor pressure of DME itself without a liquid pump. In this study, we have obtained the highest power density of 210 mW cm−2 at a temperature of 80 °C when the fuel cell is operated with the mixed fuel with 2 M methanol solution under 4 bar.
