    Abstract

    This work deals with the investigation and fabrication of Micro Direct Methanol Fuel Cells (μDMFC). They are investigated as a possible alternative for zinc-air batteries in small size consumer devices such as hearing aids. In such devices the conventional rechargeable batteries such as lithium-ion batteries have insufficiently low energy density in the range 240 Wh/L to 300 Wh/L Methanol is a promising fuel for such devices due to the high energy density, with pure methanol having an energy density of 4400 Wh/L. Using a liquid fuel also allows refueling, which can be achieved much faster than battery recharging. These features make μDMFC a suitable replacement energy source for small scale devices. Presented are two devices that delivered a peak performance of 1.7.7 mW/cm2 and 2.5 mW/cm2 while having drastically different perforated areas; 09% and 40% respectively.
