Surfactant-free hydrothermal synthesis of lithium aluminate microbricks and nanorods from aluminium oxide nanoparticles

“…For these applications, long rod-shaped or fibrous lithium aluminate forming a fine porous structure is especially desirable. 6,7 Most previous approaches to the preparation of lithium aluminate employed high temperatures and expensive precursors. 8 We have recently reported the controlled fabrication of a-LiAlO 2 and c-LiAlO 2 nanotubes via a surfactant-templated hydrothermal methods.…”

A review on MCFC matrix: State-of-the-art, degradation mechanisms and technological improvements

“…The electrolytes are usually alkaline salts [ 1 ], such as lithium and potassium carbonates, molten at MCFC operating temperatures [ 28 ]. A sufficient capillary force for their uptake and retention inside the matrix is obtained by keeping the pore diameters of the matrix smaller than those of the electrodes [ 26 , 29 ] and by having a good wettability of the electrolyte melt [ 30 ]. The optimal management is obtained when the electrolyte partially fills the electrode pores and completely fills the matrix ones.…”

A noble method for molten carbonate fuel cells electrolyte manufacturing

“…The electrolyte loss occurs by corrosion of components, creepage, reaction with cell components, and direct vaporization. This phenomenon diminishes the effective contact area of the electrodes with the electrolyte and results in reduced electrochemical reaction area, high ohmic resistance, and gas crossover or leakage [9]. The electrolyte content in each porous layer is determined by pore-size distribution in the layers.…”
