The development of proton exchange membranes as electrolytes for polymer electrolyte fuel cells operating at intermediate temperatures has been achieved combining two approaches: the preparation a cross-linked and formation covalent organic/inorganic hybrids. A covalently sulfonated polyetheretherketone with elevated degree sulfonation (DS = 0.8) was prepared by reaction HSO3Cl (SOPEEK). No degradation PEEK detected upon sulfonation, but only cross-linking via sulfonic groups SO2 moieties...

Plastics are widely produced due to their stability and ease of manufacturing, but many them quickly become a waste, breaking down into microplastics nanoplastics. While methods for the identification characterization plastic particles well consolidated, small size nanoplastics presents challenges detection analysis. Furthermore, difficulty identifying nanoplastics, analytical studies concerning effect on cells comprehensive spectroscopic still lacking. In this paper, we overcome obstacle by...

With the aim of supporting thermodynamic modeling phase equilibria molten salt mixtures, this article investigates solid phases present in NaNO3 and KNO3 binary mixtures. To that end, an innovative approach based on combined use high-temperature Neutron Scattering Analysis Differential Scanning Calorimetry was proposed. A not reported before detected close to solidus curve central part diagram, its diffraction pattern assigned a mixed nitrate phase, i.e. solution two salts.

Molten salt (MS) mixtures are used for the transport (HTF-heat transfer fluid) and storage of heat (HSM-heat material) in Concentration Solar Plants (CSP). In general, alkaline earth-alkaline nitrate/nitrite employed. Along with its upper stability temperature, melting point (liquidus point) a MS mixture is one main parameters which defines usefulness as HTF HSM medium. As result, we would like to develop predictive model will allow us forecast freezing points different compositions; thus...

Reversible solid oxide cell (RSOC) technology allows use of a single device to efficiently derive chemicals from power (power-to-fuel) and (fuel-to-power). Fuel flexibility is key aspect, as developing SOCs able operate on fuels other than hydrogen can ease their integration into existing infrastructure. In addition, H2O and/or CO2 reduction favorable in SOECs polarization losses are reduced at high temperature. Here, composite fuel electrode, 60 wt.% La0.6Sr0.4Fe0.8Mn0.2O3−δ (LSFMn) 40 (5...
