“…Suppose the stack consists of two cells in electrical series with OCVs and resistances of E 1 , E 2 and r 1 , r 2 , respectively. The maximum power of the stack is P s =( E 1 + E 2 ) 2 /4(r 1 + r 2 ) [1] The power sum of the two segmented cells is: [2] It is deduced P s -P c = -[r 1 r 2 /4(r 1 + r 2 )]( E 1 /r 1 -E 2 /r 2 ) 2 ≤0 [3] Note E 1 /r 1 and E 2 /r 2 are the short-circuit currents of cell 1 and cell 2, respectively. Only when their short-circuit currents equal to each other does P s equals to P c .…”

Cone-shaped YSZ electrolyte cylinders with a wall thickness of less than 0.2 mm were fabricated using slip casting technique. Single solid oxide fuel cell (SOFC) units were made by applying La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3 (LSCF) -Ce 0.9 Gd 0.1 O 1.95 (GDC) cathode material on the outside of the cylinders and NiO-GDC anode on the inside. A three-cell-stack was assembled by connecting the cone-shaped SOFC units in electrical series via metallic interconnects and seals. The open circuit voltage (OCV) of the three-cell-stack was 2.9 V and the maximum power was over 0.9 W at 800°C with humidified hydrogen as fuel and the ambient air as oxidant. Analysis of the impedance spectrum suggests that there is still potential to raise the stack output by improving the electrode performance.

“…Solid oxide fuel cells (SOFCs) have attracted more and more interest due to their fuel flexibility, low pollution emission and high conversion efficiency in converting the chemical energy of fuel into electrical energy [1][2][3][4][5][6] . Cone-shaped tubular SOFCs, as one of the SOFC designs, are composed of a series of cone-shaped anode-supported cell units [7][8][9] . Each unit as a single cell is connected with the next to form tubular structure, which the gas and electricity could transmission in it.…”

Cone-shaped tubular anode substrates were prepared successfully by phase inversion technique. The effect of several kinds of organic additives on the microstructure development of NiO-YSZ anode support has been investigated. The scanning electron microscopy (SEM) results of NiO-YSZ anode supports show that the organic additives can greatly influence microstructure of the anode. Electrochemical testing shows that the single cell provides a maximum power output of 350mW/cm-2 at 800°C using PEG-1000 as additive. The correlation between the electrochemical performance of single cells and microstructure of the anodes had been analyzed in detail. In addition, a two-cell-stack was assembled by connecting cone-shaped anode-supported single cells in series. The chemical performance of the stack had also been tested.
