“…For the samples before and after acid‐washing, the peak at 21.5° and 26.6° can be assigned to the peak of SiO 2 particles . While for lichen precursor and sample “before acid‐washing,” the additional peaks centered at 23.6, 29.5, 36.3, 39.8, and 42.5, 45.8° can be attributed to CaCO 3 and CaC 2 O 4 , respectively, indicating the impurity of the calcined SiO 2 /carbon nanocomposite . After acid‐washing, only diffraction peaks of SiO 2 can be observed, indicating that most of the calcium salts are removed, and this can produce nanopores.…”

A 3D SiO2/carbon nanocomposite is fabricated from lichens successfully. By acid‐washing, nanoporous structure can be generated by removing inorganic compounds. Comparing with the SiO2/carbon nanocomposite before acid‐washing, the one after acid‐washing displays decreased electrochemical reaction resistance and better electrochemical performance as anode materials for the lithium‐ion battery. At a current density of 100 mA g−1, the hierarchical porous SiO2/carbon nanocomposite after acid‐washing shows excellent cycle stability. A high reversible capacity of 583.3 mAh g−1 can still be obtained after 100 cycles, which is much higher than the theoretical capacity of graphite.

“…As a result, the solid‐state electrolyte is more suitable for practical application in comparison with the liquid electrolyte in a DCFC due to safety issues. For these reasons, the direct carbon solid oxide fuel cell (DC‐SOFC) with a ceramic oxygen ion conductor as the electrolyte has attracted a particular interest because it is an all‐solid‐state fuel cell directly operating with solid carbon as fuel without any liquid medium or purging gas . In fact, it also can be regarded as a SOFC operated with carbon fuel.…”

The performance of direct carbon solid oxide fuel cells (DC‐SOFCs) is limited by the slow carbon gasification kinetics at operating temperatures. To address this limitation, a carbon fuel loaded with Ba catalyst is developed for DC‐SOFCs to improve the electrochemical performance in this study. Ba is loaded on activated carbon in the form of BaCO3 by the wet agglomeration technique. The effect of the Ba catalyst with various contents on the electrochemical performance in single cells and fuel utilization of DC‐SOFCs are examined. Experimental results show that the optimized Ba content is 5 wt% and the DC‐SOFC with this Ba‐loaded activated carbon fuel gives the best output with a maximum power density of 328.4 mW cm−2 at 850 °C. Furthermore, the DC‐SOFC fueled by 5 wt% Ba‐loaded activated carbon operates steadily for 28.76 h with the fuel utilization of 16.0%, which is also superior to many other cells. The enhancement of cell performance suggests that Ba is an effective catalyst to the Boudouard reaction, and the catalytic mechanism is also discussed in detail.

“…As the reaction product of reaction , CO 2 would diffuse to and react with the solid carbon to produce more CO . In this way, C is continuously delivered from the solid carbon to the anode to maintain the electrochemical reaction for generating electricity . In other words, CO and CO 2 are vehicles for delivering solid carbon fuel to the DC‐SOFC.…”

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.
