Recent developments in high-temperature proton conducting polymer electrolyte membranes
Progress in the area of proton conducting polymer electrolyte membranes is intimately linked with the development of polymer electrolyte membrane fuel cells, and is today largely driven by the insufficient properties of humidified Nafion membranes at temperatures above 100 8C. Recent developments in the field include new ionomers and hybrid membranes containing inorganic nanoparticles to contro...
متن کاملEnhancing Electrochemical Performance of Heterogeneous Cation Exchange Membranes by Using Super Activated Carbon Nanoparticles
Polyvinylchloride (PVC) based heterogeneous cation exchange membranes were prepared by the solution casting technique. The effect of super activated carbon nanoparticles concentration as filler additive in membrane matrix on ionic transfer behaviors of the membrane was studied. SOM images showed uniform particles distribution and relatively uniform surfaces for the membranes. The membrane water...
متن کاملCross-linked Composite Gel Polymer Electrolyte using Mesoporous Methacrylate-Functionalized SiO2 Nanoparticles for Lithium-Ion Polymer Batteries
Liquid electrolytes composed of lithium salt in a mixture of organic solvents have been widely used for lithium-ion batteries. However, the high flammability of the organic solvents can lead to thermal runaway and explosions if the system is accidentally subjected to a short circuit or experiences local overheating. In this work, a cross-linked composite gel polymer electrolyte was prepared and...
متن کاملHopping Diffusion of Nanoparticles in Polymer Matrices
We propose a hopping mechanism for diffusion of large nonsticky nanoparticles subjected to topological constraints in both unentangled and entangled polymer solids (networks and gels) and entangled polymer liquids (melts and solutions). Probe particles with size larger than the mesh size ax of unentangled polymer networks or tube diameter ae of entangled polymer liquids are trapped by the netwo...
متن کاملRecent advances in sulfonated poly ( ether ether ketone ) based proton exchange membranes for high temperature fuel cells
Proton exchange membranes (PEMs) play an important role in the fuel cell systems. A good PEM must meet a series of requirements such as high proton conductivity, excellent mechanical strength and stability, chemical and electrochemical stability, low fuel crossover, etc. Nafion is currently the most commercially utilized electrolyte membranes for polymer electrolyte fuel cells, with high chemic...
