Promising Membrane for Polymer Electrolyte Fuel Cells Shows Remarkable Proton Conduction over Wide Temperature and Humidity Ranges

Abstract: A step in the direction of the real-life application of fuel cells (FCs) has been realized through the fabrication of a promising proton conductive membrane comprising a perfluorosulfonic-acid ionomer and nitrogen-rich poly­[2,2′-(4,4′-bipyridine)-5,5′-bibenzimidazole] (BiPyPBI). The BiPyPBI-perfluorosulfonic acid membranes displayed remarkable oxidative and mechanical stabilities with significant proton conduction over wide ranges of temperatures (40 to 140 °C) and humidities (30 to 90% RH). A 0.5 molar BiPyP… Show more

“…PEMFC, one among the different kinds of FCs, is a promising type of energy conversion device with advantages like zero CO 2 emission, low noise, high energy density, long lifetime, and last but not least, very high efficiency. 1,2 The perfluorosulfonic acid type polymers like Nafion 117 and its variants have been the most comprehensively studied PEMs on account of their superb proton conductivity, thermal stability power density, and electrochemical stability. 3 Despite that, above 80 °C, these perfluoro-PEMs exhibit high fuel permeability, alongside high cost, thus making perfluoro-PEMs ill-suited for practical application in most fuel cell applications that require operation at low temperature.…”

“…Since OsMFC is a technology that is utilized to dispose of different pollutants and produce bioelectricity, it does not need to consume electricity. With the transport of protons, water is also transported, and the density distribution of the membrane is affected by water transmission [19]. Water transmission can take place with free (osmosis) or bound (electro-osmosis) water.…”
