Proton Exchange Membrane Fuel Cells: High-Temperature, Low-Humidity Operation

2012
Proton exchange membrane fuel cells (PEMFCs) together with hydrogen represent an important storage and utilization technology for energy generated from renewable sources such as wind, solar, geothermal, or hydroelectric. This is due in part to their high energy density, low operating temperature, rapid start-up, modular design, flexibility of scale (a ...

Nafion/PTFE/silicate membranes for high-temperature proton exchange membrane fuel cells

International Journal of Hydrogen Energy, 2008
Abstract Fuel cell performance of membrane electrode assemblies (MEAs) prepared from poly(tetrafluoroethylene)/Nafion/silicate (PNS) membrane and Nafion-112 membrane were investigated. Due to the low conductivity of PTFE and silicate, PNS had a higher proton resistance than Nafion-112.

Polybenzimidazole/SiO2 hybrid membranes for high temperature proton exchange membrane fuel cells

International Journal of Hydrogen Energy, 2016
Abstract Polybenzimidazole/Silicon dioxide (PBI/SiO2) hybrid membranes were prepared and characterized as alternative materials for high temperature proton exchange membrane fuel cell (HT-PEMFC). The PBI/SiO2 membranes were cast from a PBI polymer synthesized in the laboratory and contained 5 wt. % SiO2 as inorganic filler.

Nanostructure-Based Proton Exchange Membrane for Fuel Cell Applications at High Temperature

Journal of Nanoscience and Nanotechnology, 2014
As a clean and highly efficient energy source, the proton exchange membrane fuel cell (PEMFC) has been considered an ideal alternative to traditional fossil energy sources. Great efforts have been devoted to realizing the commercialization of the PEMFC in the past decade. To eliminate some technical problems that are associated with the low-temperature

Ionic liquid doped polybenzimidazole membranes for high temperature Proton Exchange Membrane fuel cell applications

Journal of Power Sources, 2013
Abstract In this work we propose the use of the ionic liquid 1-H-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([h-mim] Ntf2) as conductive filler in a tailor-made porous, polymeric polybenzimidazole (PBI) support as proton conductive membrane for high temperature (>100 °C) fuel cell applications.

Nafion/Silicon oxide composite membrane for high temperature proton exchange membrane fuel cell

Journal of Wuhan University of Technology-Mater. Sci. Ed., 2007
Nafion/Silicon oxide composite membranes were produced via in situ sol-gel reaction of tetraethylorthosilicate (TEOS) in Nafion membranes. The physicochemical properties of the membranes were studied by FT-IR,TG-DSC and tensile strength. The results show that the silicon oxide is compatible with the Nafion membrane and the thermo stability of Nafion ...
