Reducing platinum (Pt) loading in polymer electrolyte fuel cells (PEFCs) while simultanesouly meeting performance requirements is critical for their widespread deployment. However, significant polarization losses manifest at higher current densities

Platinum alloys catalyze oxygen reduction in conventional polymer-electrolyte fuel cells [1]. The platinum is deposited on carbon, and the nature of the carbon support affects cell polarization. Two commonly used carbon blacks are Vulcan and Ketjenbl

Transport of redox active molecules across the separator in a flow battery represents an important source of inefficiency and electrolyte-imbalance-induced capacity fade [1]. This transport can occur by diffusion, migration, and convection, with driv

Redox-flow batteries can, in principle, use a wide range of active materials. However, a number of simultaneous requirements must be met to make a chemistry attractive. One of the most challenging requirements is minimizing transport of active specie

The swelling of univalent and multivalent charged polymeric networks in electrolytic solutions is studied using a classical thermodynamic model. Such systems were first modeled by Donnan, who derived an expression for the chemical potential of the io

Prof. Robert Savinell has made many important contributions to fuel-cell and flow-battery systems. Both of these systems utilize electrochemical flow cells to either generate or store electricity. Because of this commonality, one can leverage concept

The crash of TWA Flight 800 in July 1996 was attributed to an explosion in the center fuel tank. Since then, commercial airliners have been equipped with inerting systems to prevent explosive mixtures of air and kerosene vapor from forming in fuel ta

A new flow battery is presented using the abundant and inexpensive active material pairs permanganate/manganate and disulfide/tetrasulfide. A wetted material set is identified for compatibility with the strongly oxidizing manganese couple at ambient

Reducing the loading of expensive Pt-based catalysts in polymer-electrolyte fuel-cell (PEFC) catalyst layers (CLs) is imperative for wide-scale commercialization. However, a local resistance close to the Pt reaction sites becomes significant at low P
