New generation "smart electronics", such as iPad and smart phones, have a bigger appetite of electrical energy supply. It has been reported that the energy density need will increase from 500 Wh/L in 2010, to 750~1,000 Wh/L in 2015. With the energy density of the Li-ion battery is approaching limits, various alternative power supplies have been proposed and studied in recent years. Micro fuel cell, such as DMFC (Direct Methanol Fuel Cell), is considered as a potential candidate because methanol possesses much higher energy density, in terms of volume and weight, than all of the popular batteries. Recent developments about ITRI's Direct Methanol Fuel Cell (DMFC) and FC/battery hybrid will be reported in this presentation, including MEAs and FC/battery hybrid control system. Prototype examples of FC/battery hybrid system in portable electronics applications, e.g. mobile phone electricity-extender, will also be presented to show the potential of them being emerging-market products.
