摘要:
A LiCoO2-coated NiO cathode for molten carbonate fuel cell is provided, wherein the cathode is prepared by dissolving a stoichiometric amount of lithium salts and cobalt salts in a solvent with or without adding a chelating agent to give a sol or a mixed solution, impregnating a NiO electrode for MCFC into the sol or the mixed solution, and drying and calcining the resulting electrode. By using the cathode of the invention, lifetime of the cell can be extended by two or more times while maintaining cell performance.
摘要:
Disclosed are a method and an apparatus for an intact evaluation of the unit cells in a fuel cell stack. Since the degradation of the unit cells can be detected intactly, i.e. without disassembly of the stack, the time required for the detection and analysis thereof can be greatly reduced.
摘要:
Disclosed is a method for fabricating a carbon material, by which carbon fibers or carbon tubes, particularly branched carbon fibers or carbon tubes, are obtained via a so-called self-growing process without using external carbon sources. The carbon material obtained by the method has a large specific surface area and further includes a metal catalyst, and thus may be used in cell materials for a fuel cell or secondary battery, hydrogen storage devices, capacitors, solar cells, display panel or the like.

Provided are a method of preparing an electrocatalyst for fuel cells in a core-shell structure, an electrocatalyst for fuel cells having a core-shell structure, and a fuel cell including the electrocatalyst for fuel cells. The method may be useful in forming a core and a shell layer without performing a subsequent process such as chemical treatment or heat treatment and forming a core support in which core particles having a nanosize diameter are homogeneously supported, followed by selectively forming shell layers on surfaces of the core particles in the support. Also, the electrocatalyst for fuel cells has a high catalyst-supporting amount and excellent catalyst activity and electrochemical property.
