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...

Next generation cathode catalysts for direct methanol fuel cells (DMFCs) must have high catalytic activity for the oxygen reduction reaction (ORR), a lower cost than benchmark Pt catalysts, and high stability and high tolerance to permeated methanol. In this study, palladium catalysts supported on titanium suboxides (Pd/TinO2n-1) were prepared by the sulphite complex route. The aim was to impro...

This work describes for the first time a paper-based direct methanol fuel cell platform (PB-DMFC) that functions as an energy source and biosensor, assembled on simple paper substrate point-of-care (POC) applications, targeting sarcosine proof-of-concept. Specifically, strip was developed from square of Whatman paper, acting substrate. The treated with impermeable agent (paraffin solution) supp...

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...

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...

The development of direct methanol fuel cells required the attention to the electrolyte. A good electrolyte should not only be ionic conductive but also be crossover resistant. Ionic liquids could be a promising electrolyte for fuel cells. Monitoring methanol was critical in several locations in a direct methanol fuel cell. Conductivity could be used to monitor the methanol content in ionic liq...
