Characteristics of flat-tubular ceramic supported segmented-in-series solid oxide fuel cell on all sides laminating using decalcomania method

Solid oxide fuel cell components are fabricated using the decalcomania method. Then a flattened tubular segmented-series solid oxide fuel cell (SIS-SOFC) stack is prepared on each side (front, right, left and back sides) of ceramic support with a uniform thickness. SIS-SOFC laminated on all sides of...

Description
Summary:Solid oxide fuel cell components are fabricated using the decalcomania method. Then a flattened tubular segmented-series solid oxide fuel cell (SIS-SOFC) stack is prepared on each side (front, right, left and back sides) of ceramic support with a uniform thickness. SIS-SOFC laminated on all sides of the porous ceramic support show 2.6 times more active area per cell than the case involving only single side lamination. Power output increases by 2.5 times with higher open circuit voltage. This is attributed to the increase in active area per cell and sizable decrease in sheet resistance and polarization resistance by laminating the cells on all sides. For cells laminated on decalcomania paper, they show no sign of component materials penetrating through pores in ceramic support and have better interfacial bonding. Furthermore each cell component formed a uniform thickness layer.
