“…They also observed a "cold spot" upstream in the electrolyte, which was approximately 67 °C colder than the inlet temperatures. This observation is consistent with what has been reported in some experimental works [95,103]. This simulation was based on parallel flow operation.…”

“…At 650 °C, they obtained peak power densities of 698 mW/cm² (methanol), 870 mW/cm² (H2) and 467 mW/cm² (NH3) mW/cm². Meng et al [95] fabricated a 10 μm thick SDC electrolyte using a glycine-nitrate process, with Ni-SDC as the anode and Ba0.5Sr0.5Co0.8Fe0.2O3-δ BSCF as the cathode. A peak power density of 1190 mW/cm² was obtained at 700 °C.…”

“…In addition to material development, another effective way to reduce the ohmic overpotential is to fabricate thin film electrolyte, as the ohmic overpotential is proportional to the thickness of the electrolyte. As has been demonstrated by Meng's group [37], thin electrolyte with thickness of about 10 mm can be fabricated by a glycine-nitrate process, which considerably reduces the ohmic loss and enhances the SOFC performance. Despite of this successful study, long-term operation test are needed for practical application of NH 3 -fed SOFC in the coming years.…”

SUMMARYAmmonia has been identified as a promising sustainable fuel and hydrogen source for solid oxide fuel cells (SOFC). This paper aims to provide a literature review on ammonia-fed SOFCs. Both experimental studies and mathematical modeling investigations on NH 3 -fed SOFC are included and discussed. It is found that NH 3 is a technically feasible fuel for direct use in SOFCs and the performance of NH 3 -fed SOFC is comparable with that of the H 2 fed SOFC. Experimental study in literature also demonstrates that both oxygen ion-conducting electrolyte (SOFC-O) and protonconducting electrolyte (SOFC-H) can be used in NH 3 -fed SOFC, as the amount of NO x generated in a SOFC-O is negligible. Fabricating thin film electrolyte and developing more reactive electrode materials are important to improve the performance of NH 3 -fed SOFCs. Mathematical models are useful design tools for understanding the coupled transport and reaction phenomena and for optimizing the SOFC performance. Thermodynamic and pioneering 1D electrochemical models have been developed, validated and demonstrated to be reliable by the present author.

“…And the power densities of such cells are usually above 500 mW cm −2 and even close to 2 W cm −2 at temperature lower than 800 • C, depending on the electrolyte material and thickness, as well as the cell configuration and fabrication details [10,11]. The well development of fabrication techniques makes YSZ still the preferred electrolyte material for SOFC, because of its unique characteristics, such as pure ionic conductivity over a wide range of ambient conditions, high chemical and thermal stability and excellent mechanical properties.…”
