“…The 30P 2 O 5 -70SiO 2 glass family was synthesised according to the previously described sol-gel procedure with the addition of TiO 2 and poly(vinyl alcohol) (PVA) (MilliporeSigma, Saint Louis, MI, USA), described in [27]. The samples doped with poly(ethylene oxide) (PEO) were synthesised in a similar way, with addition of PEO (M w = 1 M and 200 k), supplied by Sigma/Aldrich (MilliporeSigma, Saint Louis, MI, USA).…”

“…Therefore, the design of temperature-resistant composite glassy or glassy-ceramic material satisfying these requisite operating conditions in a mid-temperature regime is a worthwhile effort. This has been challenging and important issue for numerous scientific groups for many years [1,[22][23][24][25][26][27] Thermal resistance and proton conductivity can be achieved at the same time via several methods: (i) polymer modification by means of grafting of the inorganic acid molecules; (ii) inorganic matrix synthesis with subsequent immobilisation of e.g., phosphoric acid solution; and (iii) (the most promising) synthesis of the inorganic matrix exhibiting intrinsic proteomic conductivity (i.e., phosphosilicate-glass class materials). Therefore, the rationale behind the characterisation (following synthesis) of phosphosilicate electrolyte materials is based on their capacity for serving as solid membranes which, when applied in a fuel cell operating in a mid-temperature regime, maintain the expected proton exchange rate [28,29].…”

“…Therefore, the rationale behind the characterisation (following synthesis) of phosphosilicate electrolyte materials is based on their capacity for serving as solid membranes which, when applied in a fuel cell operating in a mid-temperature regime, maintain the expected proton exchange rate [28,29]. Membranes formed from a phosphosilicate matrix consist of two main constituents, P 2 O 5 and SiO 2 , forming a homogenous structure of two interpenetrating sub-lattices present in the system [27]. Both originate from the hydrolysis of the appropriate orthosilicate and phosphate organic derivatives, followed by the thermally-driven condensation stage occurring due to water evaporation [25,26].…”

“…Therefore, basic conductivity studies performed by EIS method should be accompanied by the analysis of conduction activation energy, performed both directly and indirectly, utilising such mathematical formulations as the Meyer-Neldel rule [41,42] and Jonscher's power law [27,43]. The latter integrates dielectric relaxation data with DC conductivity variations.…”

This paper is focused on the determination of the physicochemical properties of a composite inorganic–organic modified membrane. The electrical conductivity of a family of glassy protonic electrolytes defined by the general formula (P2O5)x(SiO2)y, where x/y is 3/7 are studied by Alternating Current electrochemical impedance spectroscopy (AC EIS) method. The reference glass was doped with polymeric additives—poly(ethylene oxide) (PEO) and poly(vinyl alcohol) (PVA), and additionally with a titanium-oxide-based filler. Special attention was paid to determination of the transport properties of the materials thus modified in relation to the charge transfer phenomena occurring within them. The electrical conductivities of the ‘dry’ material ranged from 10−4 to 10−9 S/cm, whereas for ‘wet’ samples the values were ~10−3 S/cm. The additives also modified the pore space of the samples. The pore distribution and specific surface of the modified glassy systems exhibited variation with changes in electrolyte chemical composition. The mechanical properties of the samples were also examined. The Young’s modulus and Poisson’s ratio were determined by the continuous wave technique (CWT). Based on analysis of the dispersion of the dielectric losses, it was found that the composite samples exhibit mixed-type proton mobility with contributions related to both the bulk of the material and the surface of the pore space.

PrefaceOrganic-Inorganic Composite Polymer Electrolyte Membrane: Preparation, Properties and Fuel Cell Applications is intended to explore the recent developments in the area of polymer electrolyte membranes for high-temperature polymer electrolyte membrane fuel cells. This book presents a unified viewpoint of the operating principles of fuel cells, fuel cells thermodynamics and efficiency, various methodologies used for the fabrication of polymer electrolyte membranes, issues related to the chemical and mechanical stabilities of the membranes. Special attention is paid to the fabrication of electrospun nanocomposite membranes.This book discusses the developments in the fast-growing and promising area of PEM materials obtained by using hygroscopic inorganic fillers, solid proton conductors, titanium oxide, zirconia and sulphated zirconia, silica, zeolite, montmorillonite, heterocyclic solvents, ionic liquids, anhydrous H 3 PO 4 blends, heteropolyacids, etc.This book is of great importance not only to the learners but also to the more experienced fuel cell researchers, enabling a deep understanding of the organic-inorganic membranes for fuel cells, methods for the fabrication of membranes as well as properties and applications. Based on thematic topics, the book edition contains the following 17 chapters:Chapter 1 deals with the use of ionic liquids (ILs) as fuel cell electrolytes. ILs with good mechanical properties and high conductivity has great potential to fabricate polymer membranes. This chapter focuses on the recent advances in the application of ionic liquid-based polymer membranes for the development of fuel cell technology. The key factors affecting membrane performance have been nicely discussed.In Chap. 2, a review on the recent developments about organic/TiO 2 nanocomposite membranes is presented. The unique properties, such as electrical property and processability together with thermal and chemical stabilities as well as high proton conductivity at high temperatures of organic-inorganic composite systems are highlighted. v vi Preface
