Electrospun Nafion^®/Polyphenylsulfone composite membranes for regenerative Hydrogen bromine fuel cells

Journal Article Park, Jun ; Wycisk, Ryszard ; Pintauro, Peter N. ; ... - Materials

Here, the regenerative H₂/Br₂-HBr fuel cell, utilizing an oxidant solution of Br₂ in aqueous HBr, shows a number of benefits for grid-scale electricity storage. The membrane-electrode assembly, a key component of a fuel cell, contains a proton-conducting membrane, typically based on the perfluorosulfonic acid (PFSA) ionomer. Unfortunately, the high cost of PFSA membranes and their relatively high bromine crossover are serious drawbacks. Nanofiber composite membranes can overcome these limitations. In this work, composite membranes were prepared from electrospun dual-fiber mats containing Nafion^® PFSA ionomer for facile proton transport and an uncharged polymer, polyphenylsulfone (PPSU), for mechanical reinforcement, and swelling control.more »« less

Preparation of Porous Nanofibers from Electrospun Polyacrylonitrile/Polyvinylidene Fluoride Composite Nanofibers by Inexpensive Salt Using for Dye Adsorption

The high surface area of porous nanofibers enhances their performance for many applications. The present study investigated electrospinning and dye adsorption properties of polymeric nanofibers which were porous by various types of salts. The salt/polyacrylonitrile/polyvinylidene fluoride composite nanofibers were electrospun, and the inexpensive salts such as sodium chloride (NaCl), sodium bicarbonate (NaHCO{sub 3}), or calcium chloride (CaCl{sub 2}) was used to manufacture the porous fibers. Subsequently, the salt was removed by a selective dissolution, and salt extraction of nanofibers was performed with the solution of hydrochloric acid (10 wt%). Salt/PVDF/PAN and porous PVDF/PAN composite nanofibers have been applied to dye adsorptionmore »« less

Impact of Polyvinylidene Fluoride on Nanofiber Cathode Structure and Durability in Proton Exchange Membrane Fuel Cells

Journal Article Slack, John J. ; Brodt, M. ; Cullen, David A. ; ... - Journal of the Electrochemical Society (Online)

The impact of polyvinylidene fluoride (PVDF) as a binder component on the durability of Pt/C cathodes in a proton exchange membrane fuel cell membrane-electrode-assembly (MEA) during a carbon corrosion accelerated stress test (AST) was examined using electrochemical fuel cell data and visual inspection/analysis of the cathode morphology via electron-microscopy. Electrospun nanofiber cathode mat MEAs with a Nafion*/PVDF or Nafion/poly(acrylic acid) (PAA) binder or a slurry cathode MEA with neat Nafion or a Nafion/PVDF binder were investigated. The presence of PVDF had profound effects on the structure and chemical/electrochemical properties of a fuel cell cathode; its hydrophobic properties slowed the ratemore »« less

Electrospun Particle/Polymer Fiber Electrodes with a Neat Nafion Binder for Hydrogen/Air Fuel Cells

Journal Article Waldrop, Krysta ; Slack, John ; Gumeci, Cenk ; ... - ECS Transactions (Online)

Electrospun nanofiber electrodes for hydrogen/air fuel cells were prepared using poly(ethylene oxide) (PEO) carrier polymer, where previous publications used poly(acrylic acid) (PAA). Electrospinning with PEO carrier is only possible when the ink contains Nafion® in its salt form. Here, fiber electrodes were evaluated in 5 cm² membrane-electrode-assemblies (MEAs) and exhibited excellent power at high and low feed gas relative humidities. For example, a nanofiber cathode MEA made from an ink containing Na⁺-form Nafion, PEO, and Pt/C generated 822 mW/cm² at maximum power, 40% RH, 80 °C, and 200 kPa_abs, whereas PAA-based ink electrode MEAs produced 527 mW/cm².

LiCoO₂-Based Fiber Cathodes for Electrospun Full Cell Li-ion Batteries

Journal Article Self, Ethan C. ; McRen, Emily C. ; Wycisk, Ryszard ; ... - Electrochimica Acta

Particle/polymer electrospinning was used to prepare fiber mat cathodes containing LiCoO2 nanoparticles, carbon powder, and poly(vinylidene fluoride) for Li-ion batteries. The fibers had a high LiCoO2 particle content (70 wt%) which allowed for a high gravimetric capacity of 90 mAh g-1 (corresponding to 128 mAh g-1LiCoO2) at 0.1C. Cathode performance was stable in a half cell with 78% capacity retention over 200 cycles at 0.5C. Unlike previous work on electrospun LiCoO2 nanofibers prepared using sol-gel chemistry and high temperature processing, the particle/polymer fiber mat cathodes reported here were made thick with a high fiber volume fraction for high areal andmore »« less
