“…Fixed-bed downdraft gasifier with air (FDA) and a fluidized bed gasifier with steam (FBS) gasification agent are the most common gasification technologies. Both show a high potential for the coupling with SOFCs as discussed in [3,33] but differ significantly in their product gas composition due to their diverse gasification agents.…”

“…Furthermore, a hot/dry gas cleaning is suggested as the most promising for the coupling of SOFCs with gasifiers. With this cleaning option, all contaminants beside tars could be removed, including dust and sulfur compounds [3]. Hot/ dry gas cleaning improves the system efficiency avoiding steam condensation as assessed for the FDA case in an Ni/ YSZ ASC SOFC in [33].…”

“…As SOFCs are based on heterogeneous catalytic reaction processes, the main drawback of their use with gasifiers in comparison to combustion engines is the higher sensitivity to degradation of the catalytic-active surface, which decreases power output or can even lead to a failure [3]. Degradation can be caused by components of the derived product gas.…”

Solid oxide fuel cells represent a promising technology to increase the electrical efficiency of biomass-based combined-heat-power systems in comparison to state-of-the-art gas engines, additionally providing high temperature heat. To identify favorable fuel gas compositions for an efficient coupling with gasifiers at low degradation risk is of major importance to ensure stability, reliability, and durability of the systems used, thus increasing attractiveness of electricity production from biomass. Therefore, this study presents a comprehensive analysis on the influence of main gas components from biomass gasification on the performance and efficiency of a cell relevant for real application. An industrial-size electrolyte supported single cell with nickel/gadolinium-doped ceria anode was selected showing high potential for gasifier-solid oxide fuel cell systems. Beneficial gas component ratios enhancing the power output and electric efficiency are proposed based on the experimental study performed. Furthermore, the degradation stability of a SOFC fueled with a synthetic product gas representing steam gasification of woody biomass was investigated. After 500 h of operation under load at a steam-to-carbon ratio of 2.25 in the fuel gas, no performance or anode degradation could be detected.

“…It also has the flexibility to be integrated with another power generation source, water heating device and cooling device used in residential homes [4]. To further its application for large scale, the integration of SOFC with gasi cation using coal or biomass as feedstock shows potential in power generation [5][6][7].…”

With increasing demand of green energy supply with high efficiency and low CO2 emission, Solid oxide fuel cell (SOFC) has been intensively developed in recent years. And the integration of gasification with fuel cell (IGFC) shows potential in large scale power generation to further increase the system efficiency. Reliable design of multi-stacks for large system and long term stability of stacks with practical fuel gas from industrial equipment are the key for commercial application of IGFC. In this work, a test rig of 5kW SOFC system was fabricated using practical syngas from industrial gasifiers as fuel and long term test under high fuel utility was conducted to investigate the system performance. The results show that the maximum steady output power of system is 5700W for hydrogen case and 5660W for syngas case, and the maximum steady electrical efficiency is 61.24% while the fuel utility efficiency is 89.25%. The test lasted for more than 500h as the fuel utility efficiency was larger than 83%. The performances of each stack tower are almost identical at both initial stage and after long term operation. After 500h operation, the performances of stack towers just slight decrease under lower current and almost not change under higher current. Therefore, the results illustrate that the reliability of multi-stacks design and the prospect of SOFC power generation system for further enlarging its application in a MWth demonstration.

Escalation of electricity demand, its heavy dependence on combustion of natural fossil fuels, and significant emission of greenhouse gases have urged industries and researchers to develop ecofriendly and high-performance techniques for the generation and storage of energy. A range of electrochemical storage systems such as batteries, fuel cells, and supercapacitors (SCs) have been extensively developed, among which SCs have gained tremendous attention in view of their long cycle life, high specific capacitance, and particularly, high power density. [1][2][3][4] SCs are classified into two categories: pseudocapacitors and electric double-layer capacitors (EDLCs). [5] In EDLCs, the energy originates from the reversible non-Faradic reactions at the interface of electrode/electrolyte. [5] Currently, SCs (filled with carbon materials) are widely used in a large variety of applications ranging from consumer portable electric devices, memory backup systems, industrial and energy management, to emergency doors on airplanes and low-emission hybrid electric vehicles. [1] Despite advances in controlling the characteristics of carbon materials and improvements in advanced nanomaterials, such as graphene or carbon nanotubes (CNTs), activated carbons (ACs) are still the primary choice in commercial SCs due to their low cost, abundance, ease of processability, and simple production procedures. [6] From the scientific point of view, ACs are of the most versatile carbon-based electrode materials applied in SCs [7,8] due to their outstanding properties of relatively inert electrochemistry, [9] large surface area (>1000 m 2 g À1 ), [6] controllable microporous structure, favorable pore size and pore volume (>0.5 cm 3 g À1 ), [6] variable surface chemical composition, [10] and great electrocatalytic active sites for redox reactions. [11] The electrochemical performance of ACs in SCs is greatly dependent on the carbon source and fabrication method. [12] ACs used to be derived dominantly from coal and petroleumbased materials [13] ; however, in recent years, to further diminish the carbon footprint in the environment, the approach has shifted toward the use of alternative carbon resources such as waste materials. Generally, there are two types of waste resources for ACs, 1) organic wastes such as biomasses and 2) synthetic wastes such as waste polymers and fabrics.
