摘要: We present a miniature direct methanol fuel cell (micro-DFMC) using platinum sputtered microcolumn electrodes (rugged electrode) with limited amount of fuel. use the rugged electrode in order to improve power density micro-DMFC that consists two and polymer electrolyte. also design built-in chamber anode for portable electronics applications. fabricate both planar electrodes, having an identical projective area 5 mm /spl times/ mm. compare characteristics as well micro-DMFC. The shows 1.73 times larger diffusion current than from at potential 1.1 V half test. maximum 24.8 mu/W (122.4 mu/W/cm/sup 2/) 0.65V mm, while (5.6 voltage 0.08 same area.
