A new preparation method for electrolyte base-plate used for molten carbonate fuel cells(MCFC) has been presented.By using a highly dispersed Boehmite stone and LiOH

the submicrometric γ-LiAlO2 powder used for preparation of electrolyte base-plate is prepared.By adopting the prepared LiAlO2 power and a water-soluble binder

i.e.caboxy methyl cellulose(CMC)

ect.

the electrolyte base-plate used for manufacturing MCFC is prepared.The single cell of MCFC is assembled by fitting said base-plate with electrode and electrolyte salt trips

the maximum voltage of single cell reaches above 1.0 V

the maximum discharged current reaching 10 A.The aperture and porosity on the base-plate

the particle size of γ-LiAlO2 powder

and the influence of environment condition in flowing process of slurry upon the performance of base-plate have been analysed.Results show that the performance of base-plate prepared by using above-mentioned method is good

satisfying the requirements in application of MCFC.
