Polymer and Composite Membranes for Proton-Conducting, High-Temperature Fuel Cells: A Critical Review
Polymer fuel cells operating above 100 °C (High Temperature Polymer Electrolyte Membrane Fuel Cells, HT-PEMFCs) have gained large interest for their application to automobiles. The HT-PEMFC devices are typically made of membranes with poly(benzimidazoles), although other polymers, such as sulphonated poly(ether ether ketones) and pyridine-based materials have been reported. In this critical rev...
متن کاملRecent 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 کاملProton Conducting Membranes for High Temperature Fuel Cells with Solid State “water Free” Membranes
A “water free,” proton conducting membrane for use in a fuel cell is fabricated as a highly conducting sheet of converted solid state organic amine salt, such as converted acid salt of triethylenediamine with two quaternized tertiary nitrogen atoms, combined with a nanoparticulate oxide and a stable binder combined with the converted solid state organic amine salt to form a polymeric electrolyt...
متن کاملOriented MOF-polymer Composite Nanofiber Membranes for High Proton Conductivity at High Temperature and Anhydrous Condition
The novel oriented electrospun nanofiber membrane composed of MOFs and SPPESK has been synthesized for proton exchange membrane fuel cell operating at high temperature and anhydrous conditions. It is clear that the oriented nanofiber membrane displays the higher proton conductivity than that of the disordered nanofiber membrane or the membrane prepared by conventional solvent-casting method (wi...
متن کاملHigh-Temperature Proton-Conducting Ceramics Developed
with the perovskite structure and with the trivalent cation (M) substitution at the B-site to introduce oxygen vacancies. The high affinity for hydrogen ions (H) is advantageous for protonic transport, but it increases the reactivity toward water (H2O) and carbon dioxide (CO2), which can lead to premature membrane failure. In addition, there are considerable technological challenges related to ...
