“…In short, the PPD of pure PC at 800°C (205 mW cm −2 ) is equivalent to that of the catalyst‐loaded CC at 850°C (204 mW cm −2 ) . It was reported that the SO‐DCFCs operating on the pure corn cob char achieved 204 mW cm −2 or achieved 270 mW cm −2 when a Fe‐based catalyst was loaded at 800°C . In addition, a SOFC fed with the orchid tree leaf char had a PPD of 212 mW cm −2 at 850°C .…”

“…In general, biochars have unique physicochemical properties, such as textural structures and inherent catalytic constituents, which enable the fuel cells to exhibit high performances. For example, the fuel cells with different configurations operating on corn cob biochar achieved the maximum power output of 185 and 204 mW cm −2 at 750°C and 800°C, respectively . The surface morphology of the biochar is featured by the large pores with many smaller pores on their walls, which enlarge the surface area and provide more electrochemical/gasification reaction sites.…”

Summary The pomelo peel char (PC) was prepared and used as fuel for solid oxide electrolyte direct carbon fuel cells with nickel‐yttrium stabilized zirconia anode, thin‐film YSZ electrolyte, and La0.8Sr0.2MnO3 cathode. The power densities of fuel cells operating on PC and catalyst‐loaded PC (PCC) fuels achieved 309 and 518 mW cm−2 at 850°C, respectively, which are among the highest power densities reported in the literature on DCFCs. The PC exhibited superior gasification reactivity than coal char due to its unique reticulated foam carbon structure with a homogeneously distributed inherent catalyst. The stability tests at a current density of 50 mA cm−2 and 825°C indicate that the cell using PC fuel operated in a more stable manner than that using PCC, and the fuel availabilities for PC and PCC were 47.25% and 34.71%, respectively. The results suggest that PC is a promising solid carbonaceous fuel for solid oxide electrolyte direct carbon fuel cells based on its adequate gasification reactivity and high compatibility with the fuel cells.

Summary Direct carbon solid oxide fuel cell (DC‐SOFC) is a promising technology for electricity generation from biomass with high conversion efficiency and low pollution. Biochar derived from wheat straw is utilized as the fuel of a DC‐SOFC, with cermet of silver and gadolinium‐doped ceria as the material of both cathode and anode and yttrium stabilized zirconia as electrolyte. The output performance of a DC‐SOFC operated on pure wheat straw is 197 mW cm−2 at 800°C and increases to 258 mW cm−2 when 5% of Ca, as a catalyst of the Boudouard reaction, is loaded on the wheat straw char. Higher power and fuel conversion utilization are achieved by using Ca as the Boudouard reaction catalyst. X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectrometer, and programmed‐temperature gravimetric experiment are applied to characterize the leaf char. It turns out that the wheat straw char is with porous structure and composed of C, K, Mg, Cl, Fe, and Ca elements. The effects of the Ca catalyst on the Boudouard reaction, the performance of the DC‐SOFCs operated on the wheat straw char, and the economic advantages of the wheat straw char are demonstrated and analyzed in detail.

Direct carbon solid oxide fuel cell (DC‐SOFC) is a promising energy conversion system, which can directly convert the chemical energy of biomass into electrical energy with high efficiency and low pollution. Herein, a microtubular DC‐SOFC fueled with the biochar derived from pepper straw for electrical power generation is reported. The DC‐SOFC operated on pepper straw char gives a maximum power density of 217 mW cm−2, comparable with 252 mW cm−2 for that with hydrogen fuel at 850 °C. Moreover, the lifetime of the DC‐SOFC reaches 21 h at a discharge current of 100 mA with the fuel utilization of 44.4%. The pepper straw char is characterized physically by scanning electron microscopy, energy‐dispersive spectrometer, X‐ray diffraction, Raman spectroscopy, thermogravimetric analysis, and differential scanning calorimetry. The results demonstrate that the pepper straw char contains natural catalysts in itself and their contribution on the electrochemical performance of the microtubular DC‐SOFC is analyzed in detail.
