Solid oxide fuel cells (SOFCs) have been considered as one of the most efficient power generators that can directly convert chemical energy in the natural gas, biomass, or coal‐derived gas to electrical energy. Various contaminants in syngas are capable to cause catalyst malfunction and cell performance drop, limiting fuel cell to a wide application. The effects of PH3 and CH3Cl fuel impurities on...
In this work, interconnect/electrode sheet/interconnect sandwiches are assembled by designing interfacial contact between interconnects and electrodes for planar solid oxide fuel cells (SOFCs). Their area specific resistance (ASR) values of different contact methods under isothermal oxidation and thermal cycling are recorded by four‐point method. The ASR of SUS430/Ni–YSZ/SUS430 anode sandwich with...
This work investigates the effect of contact between electrodes and alloy interconnects on output performance of solid oxide fuel cell (SOFC) stacks. The measured maximum output power density (pmax) of the unit cell increases from 0.07 to 0.1 W cm–2 by increasing the tip area of the interconnect from 40 to 60 cm2. The pmax increases from 0.07 to 0.15 W cm–2 upon the addition of nickel foam and Ag...
