| Abstract: | The solid oxide fuel cell (SOFC) consists of four electrochemically active
solid components, viz., a porous cathode, a porous anode, a dense electrolyte
and a dense interconnect to form stacks. Tape casting technology involves the
dispersion of inorganic ceramic particles (electrolyte) in a liquid (solvent)
medium followed by the addition of organic binders, plasticizers and
deflocculating or defoaming agents to fabricate a thin ceramic sheet. In this
research work, the selection and loading level of additives have been optimized
to fabricate alternate electrolyte components of SOFC viz. La0.9Sr0.1Ga0.8Mg0.2O3- , Ce0.90Gd0.10O2- and Ce0.80Sm0.20O2- by
tape casting technique. In order to remove the organic substances from green
electrolyte components and sintering, the heat treatment of green tapes has
been optimized by thermogravimetry differential thermal analysis (TG-DTA). The
surface morphology of both green and pre-sintered components has been studied
by Scanning Electron Microscopy (SEM) |
