“…Various carbon-based materials have been investigated experimentally and theoretically as electrode materials for energy storage and conversion devices such as in fuel cells [60][61][62][63][64] , supercapacitors (SCs) [65][66][67][68][69][70] and LIBs [71][72][73][74][75], all aimed at improving the specific capacity, cyclic efficiency, lifetime, power and energy density of the energy storage devices [71,76]. The electrochemical insertion of sodium ion in carbon based materials started in the 1980's.…”

“…22 Moreover, gadolinia-doped ceria (GDC), samaria-doped ceria (SDC), and other ceria-based electrolytes have received a great deal of attention because of their ability to conduct oxygen ions at lower temperatures than YSZ. [23][24][25][26][27] The cathode in SOFCs is usually composed of porous perovskite materials, which are oxides characterized by relatively good electronic conduction at high temperatures in an oxidizing atmosphere. The most widely used cathode materials in SOFCs are strontium-doped lanthanum manganite (La 1−x Sr x MnO 3 , or LSM), strontium-doped lanthanum colbaltite (La 1−x Sr x CoO 3−δ , or LSC), the relatively novel strontium-doped lanthanum ferrite (La 1−x Sr x FeO 3−δ , or LSF), and strontium-doped lanthanum cobalt ferrite (La 1−x Sr x Co 1−y Fe y O 3−δ , or LSCF).…”

“…Studies on influence of carbon properties in Solid Oxide Fuel Cell (SOFC) are scarce. [11][12][13] This could be due to difficulty in direct oxidation of solid carbon in SOFCs. Nevertheless, recent work indicates that amorphous carbon is electrochemically more active than graphitic carbon.…”

Previous experimental results have shown that a system with molten carbonate and solid oxide electrolyte is feasible for Direct Carbon Fuel Cell (DCFC). A study is presented to investigate cell performance with a range of solid carbon (i.e. coals, biochars, graphite) and operation mode in this hybrid electrolyte system. The results show that less crystalline coal with high fixed carbon, low sulfur, medium volatile material and moisture is best suited to this system. Using high rank of fuel such as anthracite coal, good cell performance can be obtained only by elevating temperature and with adequate pretreatment to remove impurities. Discussion of cell operation indicates that cell degradation and operation failure were due to coal agglomeration, ash buildup, and limited fuel supply in potentiostatic mode. Instead, galvanostatic operation gave stable cell performance over 60 hours. This result allows better understanding of anode reaction mechanism on the hybrid electrolyte system. Thus, long-term operation is promised when suitable solid fuel and optimized operation parameters are applied. Direct Carbon Fuel Cell (DCFC) is a promising technology to use solid carbon for energy production. This technology allows direct conversion of chemical energy to electricity, thus giving a high thermodynamic efficiency, i.e. 100%, when carbon is oxidized to carbon dioxide. The concept of DCFC is simple. Solid carbon is fed to a fuel cell and electrochemically oxidized at the anode to produce electricity.1-3 Pure product, carbon dioxide (CO 2 ), is obtained in complete oxidation and is easy for carbon sequestration. Furthermore, application of DCFC benefits from sufficient fuel supply with abundant coal and biomass in the world. These advantages as well as established infrastructure of transportation, storage, and processing for solid carbon make a DCFC feasible and very attractive.One of design challenges to develop a DCFC is choice of fuel. 4Despite large reserves of solid carbon available, different sources of carbon have varying activity and indeed affect DCFC performance. In the past, many attempts have been made to evaluate effect of solid carbon on DCFC for electric power generation. Cooper et al. 5 reported cell polarization on nine particulate carbon derived from fuel oil, coal, biochar, petroleum coke, etc. The highest discharge rate, 100-125 mA cm −2 at 0.8 V and 800• C, was obtained with biochar-derived carbon. They found that properties of carbon fuel which control discharging rates are (i) crystallographic disorder, (ii) electrical conductivity, (iii) active surface sites, and (iv) sulfur and ash impurities. Less graphitized and high disordered carbon such as chars is more reactive to oxidation; however, this property counterbalances electrical conductivity since chars are poor conductors. By contrast, neither particle size, surface area, nor morphology was found to have much impact on the electrochemical discharge rate. Moreover, Zhu et al 6 investigated factors that determine performance of carbon fuel in the D...
