Compact bipolar plate-free direct methanol fuel cell stacks.
Fuel cells with a PtAu/C anode and a Pr-doped Mn(2)O(3)/C cathode were stacked without using a bipolar plate, and their discharge properties were investigated in a methanol aqueous solution bubbled with air. A three-cell stack exhibited a stack voltage of 2330 mV and a power output of 21 mW.
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...
متن کاملDesign of a New Micro Direct Methanol Fuel Cell Using MEMS Technology
In this paper, a special micro DMFC using MEMS technology is designed to work in a circumrotating condition, which providing power using inertia over-load. The designed cell is a cylinder, anode channel is inside, cathode is outside and exposes to the air. When the overload exceeds the critical value, the liquid inside reserve tank will splash and comes into the two electrodes, and then the cel...
