Abstract
Two types of anode supported solid oxide fuel cell (SOFC)
NiO-YSZ/YSZ/GDC/LSCF with the same structure and different manufacturing
process were tested. Gas leakage was suspected for
cells manufactured with screen printing technique. Effective leak
current
densities for both types of cells were calculated.
Their performances of electrochemical impedance spectroscopy (EIS) were
compared and distribution function of relaxation
times (DRT) technique was also used to find the clue of gas leakage.
Finally,
thinning and penetrating holes were observed in
electrolyte layer, which confirmed the occurrence of gas leakage.
