The Direct Methanol Fuel Cell (DMFC) has attracted much attention due to its potential applications as a power source for transportation and portable electronic devices. Based on the advantages of the scaling laws, miniaturization promises higher efficiency and performance of power generating devices and the MicroDMFC is therefore an emergent technology. In this work, a set of experiments with ...

A novel proton exchange membrane has been prepared using sulfonated poly(styrene-divinylbenzene) resin(SPSDR)–polyethylene(PE). The membrane is characterized by FT-IR, SEM and TGA/DSC. Water uptake, oxidative resistance, ionic conductivity and methanol permeability are measured to evaluate its performance in a direct methanol fuel cell. The on-set degradation temp...

Ethanol is receiving great interest as an alternative fuel. Methanol is another alcohol fuel that could serve as a replacement for gasoline. Although it is currently receiving much less attention, it has the potential to play an important role. Like ethanol, methanol also has the advantage of being a liquid fuel and it can be produced from gasification of a variety of feedstocks using well esta...

Direct methanol fuel cells are regarded nowadays as promising energy sources for portable electronic devices. Numerical models can be very useful for addressing the exploration of the fuel cell performance, without the development of many prototypes, which can be very expensive due to the presence of rear materials. Analytical models are particularly suited for investigating the cell performanc...

The high efficiency and energy density of miniaturized fuel cells provide an attractive alternative to batteries in the portablepower-generation market for consumer and military electronic devices [1-3]. The best fuel cell efficiency is typically achieved with hydrogen, but safety and reliability issues remain with current storage options. Consequently, there is continued interest in reforming ...

This paper presents a silicon-based micro direct methanol fuel cell (μDMFC) stack with compact stacked structure and a unique shared anode plate. The μDMFC stack consists of two fuel cells in electrically parallel connection, while the fuel transport is arranged in series. Experimental results show that the μDMFC stack generates a power density of 12.71mW/cm, almost twice as much as that of a s...
