Design and development of micro direct methanol fuel cell (μDMFC) for portable application

A passive, air-breathing single cell and a multi-cell stack micro direct methanol fuel cell with 1.0 cm2 active area were designed, fabricated and tested. The fuel cell was completely passive without any ancillary device such as pump. Oxygen was taken from the surrounding air, and the methanol solut...
