Current Status and Roles of Proton Exchange Membrane in Direct Methanol Fuel Cell Systems

摘要: Mobile devices in the next generation such as camera, cell phone, network, Note PC, etc. require higher power and energy sources due to convergences of various functions. Direct methanol fuel (DMFC) has been focused an attractive source, but there are critical issues involved its commercialization with regard core technologies materials, components, system. The requirements key differentiated from applications supply methods. Here, roles proton-conducting membrane discussed current status DMFC systems is terms proton conductivity, permeability, water management. Materials perfluorinated partially fluorinated membranes, hydrocarbon composite other modified ionomers have studied. These would explain role membranes for commercialization.
