The burner to establish 2x2 array of microflames of DME with air coflow around each microflame has been developed and applied to a direct flame fuel cell. This power generation system has been tested and showed that the max power density is attained at corresponding equivalence ratio of 1.45 and at fuel flowrate of 60 sccm. The obtained optimum max power density is 0.49W/cm^2, which is better than previous studies. However, the conversion efficiency is only 0.46%, which means that it needs to become at least 4.3 times larger to have larger energy density than that of lithium polymer buttery.
