1、Performance of anode-supported SOFC using novel ceria electrolyte,Jin Soo Ahn,Shobit OmarPresented by ZhouQiangShanghai institute of ceramics,CAS,Ways of generating electricity,1 high energy efficiency2 quiet and nonpolluting,Advantanges of SOFCs,Structure of SOFC,Properties of SOFCs,1 Power density
2、 the amount of power per unit volume.2 ASR(area specific resistance)the ASR directly related to ohmic loss of the cell.,Preparation of the novel electrolyte,Sm0.075Nd0.075Ce0.85O2-(SNDC),Ce(NO3)36H2O Sm(NO3)36H2O Nd(NO3)36H2O,co-precipitation,+ammonia,precipitate,Dried at 80 for12h,agglomeratedpowde
3、r,ground,fine particles,Calcined at 900 for 10h,SNDC powder,Preparation of a single cell,1 Ni-GDC anode supports were synthesized by tape casting.2 cathode was prepared by mixing LSCF and the GDC powder 3 the electrolyte was dip-coated onto the anode surface,and was brush-painted onto the SNDC elect
4、rolyte.every process the sample should be sintered at certain temperature.,Test the properties,1 Scanning electron microscope(SEM),2 Power density,3 Impedance spectrum,conclusion,a.At 650,a maximum power density of 1.43 Wcm-2 was achieved.b.The total ASR at 650 was only 0.105cm2.c.SNDC is a promising alternative electrolyte for intermediate temperature solid oxide fuel cells(SOFCs).,Thank you!,
