DOI: 10.1016/j.coelec.2017.10.020
Abstract: Summary Low proton conduction, resulting from interrupted H+ hopping between water molecules to form H3O+ ions, significantly complicates the operation of proton exchange membrane fuel cells at intermediate temperatures (80–120°C) and low relative humidities ( read more here.

DOI: 10.3390/polym12061431
Abstract: Composite membranes based on different wt percentages of meso-tetrakis-(4-sulfonatophenyl)porphyrin (TPPS) embedded in a medium sulfonation degree (50%) sulfonated poly(etheretherketone) (s-PEEK) were investigated. The successful introduction of porphyrin into the membranes and the characterization of its… read more here.
