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...
WC/graphitic carbon nanocomposite was in situ simultaneously obtained from anion exchange resin-WO(4)(2-)-[Fe(CN)(6)](4-) complex, which could act as a highly efficient catalyst support for the direct methanol fuel cell.
A 40 wt% Pt/C cathode electrocatalyst with controlled Pt particle size of approximately 2.9 nm showing better performance than commercial catalyst for direct methanol fuel cell was prepared by a polyol process with water but without using stabilizing agent.
This paper examines polymer film morphology and several important properties of polyethylene-graft-sulfonated polyarylene ether sulfone (PE-g-s-PAES) proton exchange membranes (PEMs) for direct methanol fuel cell applications. Due to the extreme surface energy differences between a semi-crystalline and hydrophobic PE backbone and several amorphous and hydrophilic s-PAES side chains, the PE-g-s-...
