A direct carbon solid oxide fuel cell (DC-SOFC) was assembled and tested. The cell was a tubular SOFC-like structure, using YSZ as electrolyte, silver paste as anode and cathode, and graphite as fuel. At the testing temperature 800{degree sign}C, the open circuit voltage of the cell was 0.85V and the maximum power reached 47mW with the active cell area of 5.08 cm2. In the lifetime measurement, the cell current was maintained at 71mA. After running 3h, the cell voltage dropped from 0.62V to 0.22V and the discharge value calculated was 771C.

“…Many studies have demonstrated the feasibility of this design. [35][36][37] And in our previous study, we have found that (Ni 0.75 Fe 0.25 -5%MgO)/YSZ is a promising anode material for SOFCs operating on methane fuel. 38 We conjectured that MgO may strengthen the anode allowing it to endure the stress caused by carbon fiber growth, or MgO can suppress carbon fiber growth.…”

An anode-supported cone-shaped tubular solid oxide fuel cell (SOFC) with (Ni0.75Fe0.25-5%MgO)/YSZ anode is prepared and is directly operated on dry and moist CO fuel, respectively. At 800°C, the cell exhibits a maximum power density (MPD) of 424 mWcm−2 for dry CO and 388 mWcm−2 for moist CO. The durability test results show no significant degradation in performance for this kind of cell operated on either dry or moist CO after an operation time of 40 h at a constant current of 83 mA cm−2 at 800°C, while the cell with Ni/YSZ anode, in comparison, fails rapidly. A two-cell-stack based on the above mentioned SOFCs is fabricated and tested by direct utilization of moist CO as fuel. The SOFC stack presents an open circuit voltage (OCV) of 2 V and a maximum output power of 4 W at 800°C. And it exhibits good stability and dependability during an operation time of 90 h. The results demonstrate that (Ni0.75Fe0.25-5%MgO) /YSZ would be a promising anode for SOFC operating on CO or CO-contained fuels.

Summary In accomplishment of massive energy demand, the solid oxide fuel cells (SOFCs) have proven as apotheosis candidates due to their high energy conversion efficiencies, low pollution exhaust, fuel flexibility, and environmental friendliness which make these the most promising alternatives to conventional electricity generators. Despite numerous advantages of SOFCs, large‐scale industrial applications are yet to be realized owing to their high operating temperatures (800°C‐1000°C). To lower the operating temperature, it is crucial to minimize ionic resistances which can be accomplished by reducing the electrolyte thickness to lesser than 5 μm. Therefore, present article embraces a concise review on conventional materials, designs, and generations of SOFCs with their compatibility and drawbacks. The strengths and limitations of conventional and advanced tools for fabricating thin film based SOFCs (TF‐SOFCs) as well as the associated properties of electrolytes and electrodes are thoroughly examined, and further route cast is provided to attain better performance. The present review encourages the development of TF‐SOFCs using advanced techniques employing ultrathin single and bilayer electrolytes which can have potential to reduce the operating temperature of SOFCs from 450°C to 600°C region and pave the way for global commercialization.
