Electrochemical and flow characterization of a direct methanol fuel cell
Two-phase phenomena, i.e. bubble flow in the anode and water flooding in the cathode, are critical to design of high-performance direct methanol fuel cells (DMFC). A 5 cm2 transparent DMFC has been developed to visualize these phenomena in situ. Two types of membrane-electrode assembly (MEA) based on Nafion® 112 were used to investigate effects of backing pore structure and wettability on cell ...
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 کاملeffect of methanol concentration and channel depth on performance of direct methanol fuel cell
effect of methanol concentration and channel depth of bipolar plates on the performance of single direct methanol fuel cell was investigated experimentally. the membrane used in this experiment was nafion117. dimension of the single cell were 10cm 10 cm. methanol concentrations of 0.50, 1.0, 1.5, 2.0, 3.0 molar were used. channel depth of the bipolar plates were chosen to be 1.0, 1.5, 2.0 mm, a...
