Experimental Investigation of a Passive Direct Methanol Fuel Cell
Direct methanol fuel cells (DMFC) are getting increasing attention as a possible power source for application in the field of power electronics where the energy requirements are relatively small. The major advantage of the DMFC is their high energy density in comparison to the conventional batteries. In this study, the performance of a passive direct methanol fuel cell was investigated under fi...
متن کاملTransient investigation of passive alkaline membrane direct methanol fuel cell
Passive direct methanol fuel cell (DMFC) is considered as an attractive power source for portable devices. In this study, a transient multiphase model for passive alkaline anion exchange membrane DMFC (AAEMDMFC) is developed. The results show that the power density decreases during the operation and is more difficult to maintain stable with higher current density or lower voltage. The fuel effi...
متن کاملSelectivity of Direct Methanol Fuel Cell Membranes
Sulfonic acid-functionalized polymer electrolyte membranes alternative to Nafion(®) were developed. These were hydrocarbon systems, such as blend sulfonated polyetheretherketone (s-PEEK), new generation perfluorosulfonic acid (PFSA) systems, and composite zirconium phosphate-PFSA polymers. The membranes varied in terms of composition, equivalent weight, thickness, and filler and were investigat...

متن کاملDirect Methanol Fuel Cell Thermodynamic Simulation
The direct methanol fuel cell (DMFC) is considered a viable power production technology for portable electronics equipment (10’s-100’s watts) and transportation vehicles (10’s-100’s kilowatts). Since methanol is relatively inexpensive and a reformer or other fuel processing equipment is not required for the DMFC, this power system has the potential to be low cost, compact, reliable and fuel eff...
