“…Direct carbon solid oxide fuel cell (DC-SOFC) is an allsolid-state device that directly converts chemical energy of carbon fuel into electrical energy. It is feasible to use raw biochar as a fuel in direct carbon fuel cells (DCFC) or hybrid carbon fuel cells (HCFC) (Jafri et al 2018;Kacprzak et al 2016). Biochar as an electrode or catalyst has a promising prospect in microbial fuel cells (Deng et al 2018;Huggins et al 2016).…”

After entering the twenty-first century, biochar has become a focal point of multidisciplinary research because of its special characteristics, broad application, and promising development prospects. Basic and applied research on the application of biochar in the areas of agriculture, environment, and energy have increased dramatically in the face of food security, environmental pollution, and energy shortage. Although there are some disputes about biochar research, many studies have demonstrated the importance of biochar research from the perspective of scientific advancement and practical application. This paper briefly recalls the history of biochar application; introduces research progress on the basic characteristics of biochar and its associated production technologies; summarizes the research status and existing problems of biochar application in the areas of agriculture, environment, and energy; and analyzes the potential problems and development trends of biochar research in the future.

“…Qiu et al [257] reported the development of a direct carbon solid oxide fuel cell that was able to convert the chemical energy of biochar into electricity with high efficiency. The authors used biochar that had been derived from several biomasses (wheat straw, corncob, and bagasse), reaching a peak power densities of 260 mW/cm 2 at 800 • C. A detailed study of direct carbon fuel cells was reported by Kacprzak et al [258][259][260]. Firstly, the authors compared graphite rod and biochar from an apple tree that was pyrolyzed at 600 • C in a molten salt mixture of sodium and potassium hydroxide, and they found an optimum operative condition at 400 • C with a NaOH/KOH ratio of 1.…”

Biochar is the solid residue that is recovered after the thermal cracking of biomasses in an oxygen-free atmosphere. Biochar has been used for many years as a soil amendment and in general soil applications. Nonetheless, biochar is far more than a mere soil amendment. In this review, we report all the non-soil applications of biochar including environmental remediation, energy storage, composites, and catalyst production. We provide a general overview of the recent uses of biochar in material science, thus presenting this cheap and waste-derived material as a high value-added and carbonaceous source.

“…Furthermore, the determined electrochemical efficiency was 59% (at the voltage of 0.65 V) and was barely by 5% lower than theoretically achievable in the conditions studied. Fuel utilization factor was 95%, which means that most of the fuel was converted into electricity during fuel cell operation …”

“…Carbon fuel cells offer a range of benefits, among which are the use of solid carbonaceous fuels, eg, fossil coals or carbonized biomass of various origins (even organic wastes like coffee grounds or wastepaper), very high theoretical efficiency (100%), and practical efficiency (50‐80%), which translates into minimum 50% reduction of CO 2 emissions per unit of generated electricity (compared with the conventional heat power plant) and low emissions of pollutants (eg, SO 2 , NO x , fly ashes). Furthermore, DCFCs can represent the element of distributed energy systems that generate electricity and heat from biomass with power from several to several hundred kWe.…”

Summary Among numerous modern high‐performance energy technologies that allow for conversion of chemical energy into electricity and heat, the most interesting are direct carbon fuel cells (DCFCs). They are the only ones among all types of fuel cells that allow for a direct conversion of chemical energy stored in the solid fuel (carbon) into electricity. Furthermore, they are characterized by high performance, which is not limited due to the Carnot's rule, low emissions of such substances as SO2, NOx, fly ashes and others, and a relatively simple design since there are no moving components. Nowadays, DCFCs have been developed all over the world. These cells differ first and foremost in the electrolyte they use. The type of electrolyte determines both configuration of the device and operating temperature. The paper discusses current state of knowledge concerning DCFC technology with alkaline (hydroxide) electrolyte and presents the results of research and development studies concerning such cells all over the world. Furthermore, main factors and parameters that impact on the operation of individual cells and potential challenges that have to be overcome in order to develop these technologies were characterized and discussed.
