dc.description.abstract | The degradation of cathode materials due to the so-called NiO dissolution problem is one of the most critical issues restricting the long-term operation of molten carbonate fuel cells (MCFCs) To overcome this problem a modified NiO powder is prepared by the annealing of a pre-mixed powder consisting of Ni powder and CO3O4 nano-particles (n-Co3O4) at 650 degrees C Annealing above 300 degrees C plays an important role in converting the physically bound mixed oxide system to a chemically bound system and therefore the separation of n-Co3O4 from Ni is prevented This modification leads to the formation of a Ni0 9Co0 1O solid solution and the lithiated Ni0 9Co0 1O has a core-shell structure that consists of different Li contents Whereas the core phase has a low concentration of lithium the outer layer is a highly lithiated phase Since the highly lithiated outer phase acting as a barrier minimizes the dissolution of NiO the modified cathode demonstrates good electrochemical properties and chemical stability under actual operating conditions This study can provide an effective way to mass produce MCFC cathode materials (c) 2010 Elsevier B V All rights reserved | - |
