Experimental and modeling studies of a micro direct methanol fuel cell
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 ...
متن کاملExperimental 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 کاملA Micro Direct Methanol Fuel Cell with Self-pumping of Liquid Fuel
This paper introduces a micro direct methanol fuel cell (μDMFC) with an imbedded self-pumping mechanism to deliver liquid fuel. The fuel is propelled without any power consuming component (e.g., a pump), while removing the CO2 bubbles generated by the fuel-cell electrochemical reaction of the system. Furthermore, the pumping rate is self-regulated by the reaction, i.e., by the load. By eliminat...
متن کاملThe micro-scale analysis of the micro direct methanol fuel cell
In this paper, the behavior of micro-scale effect in a micro direct methanol fuel cell (mDMFC) is investigated through both simulations and experiments. A model is built to describe the methanol distribution in the diffusion layer with different feature sizes. In addition, the dynamic movement of a single CO2 bubble is also simulated to study the two-phase characteristics in the micro channels ...
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...
