The increase in the concentration of electrolytes for secondary batteries has significant advantages terms physicochemical and electrochemical performance. This study aims to explore a highly concentrated electrolyte Na-ion using ternary salt system. eutectic composition Na[N(SO2F)2]–Na[N(SO2F)(SO2CF3)]–Na[SO3CF3] molten system increases solubility into an organic solvent, enabling use batterie...

A future, robust energy portfolio will include, together with fossil fuel technologies and nuclear systems, a mix of renewable energy systems. Within each type of system there will also be variants used to strengthen a nation's baseload and/or peak power requirements. Among renewable energies, solar thermal systems are particularly promising in terms of their capability of contributing to the b...

The effect of varying the CO-CO2 and CO2-N2 ratios was investigated in the presence of coal in a specially designed 3-electrode setup, used to simulate the anode compartment in a hybrid direct carbon fuel cell (HDCFC). The HDCFC consists of a hybrid between a molten carbonate and a solid oxide fuel cell (SOFC). It was shown that the cell performance improved with increased CO2 content in the CO...

Introduction World economy at present relies on burning fossil fuels to produce affordable energy. A consequence of the use of these fuels is the emission of large amounts of carbon dioxide (CO2) to the atmosphere creating environmental problems such as global climate warming. In the near future, if CO2 emission regulations are enforced, industry will require improved technologies for the effic...

Fuel cells will become more attractive to mainstream electricity users as they improve in capability and decrease in cost. Molten Carbonate Fuel Cell (MCFC) stack dynamic model was developed to analyze a spectrum of dynamic responses, and a simplified process flow diagram of a fuel cell power plant is presented. The neural network (NN) computing architectures suggest that they may be good candi...
