Study of Dehydrated Salts: Electrolyte for Intermediate Temperature Fuel Cell

Abstract

Fuel cells are receiving growing interest in recent years since they represent one of the most promising energy source to reduce pollutant emission. We propose some new dehydrated salts as an electrolyte in the intermediate temperature fuel cell. The proton conduction in the dehydrated salts was established by the study of DTA/TGA, infrared spectroscopic study, transference number, bulk electrical conductivity measurement and emf study. The electrical conductivity of the dehydrated salts becomes ionic and increases 100-1000 times in the hydrogen ambient with respect to vacuum.

Large‐Area, All‐Solid, and Flexible Electric Double Layer Capacitors Based on CNT Fiber Electrodes and Polymer Electrolytes

“…The mixture of PYR14TFSI ionic liquid, PVDF-HFP copolymer and Li salt has been investigated as electrolyte in conventional lithium-ion batteries and, in combination with CNT fiber cathode in lithium-oxygen battery [31] . Although PVDF-HFP is a common polymer component of PE used with several ionic liquids for solid EDLC [36,37] , its combination with PYR14TFSI has not been investigated so far. Uniform and transparent membranes with no microphase separation were produced with a concentration of IL in PVDF-HFP between 50…”

Dioxidomolybdenum(VI) Complexes of Tripodal Tetradentate Ligands for Catalytic Oxygen Atom Transfer between Benzoin and Dimethyl Sulfoxide and for Oxidation of Pyrogallol

“…This resulted in the generation of a new band characteristic of purpurogallin at λ = 417 nm ( Figure 11). [35,36] Thus, the reaction appeared to follow the peroxidase pathway. However, the reactivity of 2 with H 2 O 2 did not indicate the formation of any peroxide intermediate, as no visible spectral or colour changes were observed.…”

“…The yellow solid that separated as the reaction mixture cooled to room temperature was collected by filtration, washed with cold MeOH and dried under vacuum, yield 0.485 g (70 %). C 36 Oxotransfer Activity: A solution of benzoin (1.06 g, 5 mmol), catalyst (0.0030 g, 5.72 μmol) and DMSO (1 mL) in acetonitrile (10 mL) was maintained at 80°C for 24 h. The progress of the reaction was monitored by HPLC with MeCN/H 2 O/TFA mixtures (60:40:0.02).…”
