The regenerative H 2 /Br 2-HBr fuel cell, utilizing an oxidant solution of Br 2 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(More)
A class of nanofiber-based polymer/particle proton exchange membranes ͑PEMs͒ is described for use in H 2 /air fuel cells that operate at low humidity. The membranes were fabricated from electrospun nanofibers composed of sulfonated poly͑arylene ether sulfone͒ ͑sPAES͒ with sulfonated polyhedral oligomeric silsesquioxane ͑sPOSS͒ as a proton conductivity(More)
There is a need for polymeric hydrogen/air fuel-cell membranes that can efficiently conduct protons at moderate to high temperatures for wet and dry gas feeds. The US Department of Energy (DOE), for example, set an exceedingly stringent preliminary target for membrane conductivity, 0.10 S cm À1 at 120 8C and 50 % relative humidity (RH). [1] Herein, we(More)
