“…The differences in cell operation, associated with a particular fuel, are probably the effect of the fuel specific surface area (and thus the reaction kinetics), or are brought about by the, so called, crystallographic disorders and the presence of some microelements that may support or catalyze the electrochemical reactions in the DCFC [1]. The above assumption needs, however, some further investigation.…”

“…The experimental results obtained so far by several authors, e.g. [6][7][8][9], are quite promising and thus further investigations are led with increased interest [1,3,4,10,11]. The DCFC provides excellent conditions for direct conversion of fuel's chemical energy into electricity without the combustion process and with no use of any 'intermediate' technologies or machinery (e.g.…”

“…The maximum theoretical efficiency of a DCFC may reach 100% [1], however in practical cases the efficiencies of energy conversion of up to 80% may be reached; calculated on a higher heating value (HHV) basis. Such efficiency seems to be sufficient for numerous practical applications and furthermore is still higher than the efficiency of hydrogen-fuelled fuel cells [2].…”

The direct carbon fuel cell technology provides excellent conditions for conversion of chemical energy of carbon-containing solid fuels directly into electricity. The technology is very promising since it is relatively simple compared to other fuel cell technologies and accepts all carbon-reach substances as possible fuels. Furthermore, it makes possible to use atmospheric oxygen as the oxidizer. In this paper the results of authors' recent investigations focused on analysis of the performance of a direct carbon fuel cell supplied with graphite, granulated carbonized biomass (biocarbon), and granulated hard coal are presented. The comparison of the voltage-current characteristics indicated that the results obtained for the case when the cell was operated with carbonized biomass and hard coal were much more promising than those obtained for graphite. The effects of fuel type and the surface area of the cathode on operation performance of the fuel cell were also discussed.

Abstract. In this paper, the impact of the physicochemical properties of carbonaceous solid fuels on the performance of a direct carbon solid oxide fuel cell (DC-SOFC) was investigated. High-purity synthetic carbon powders such as carbon black N-220 and Carbo Medicinalis FP5 were chosen for analytical and electrochemical investigations in a DC-SOFC. The research focussed on choosing an optimised, cost-effective, high-purity carbon powder which could be applied as a solid reference fuel for all tests performed on a single DC-SOFC cell as well as on DC-SOFC stack constructions. Most of the electrochemical investigations described in this paper were performed using square DCSOFCs with dimensions of 5 × 5 cm. The relationship between structure, physicochemical properties, and electrochemical reactivity in a DC-SOFC was analysed.

“…While coal remains the most available and abundant fuel source around the world (60% of all global sources), highly efficient fuel technologies are required to minimize the severe environmental impact of electric energy production from coal [3]. In this regard, several studies [4][5][6][7] have presented novel concepts for the direct electrochemical oxidation of carbon (coal or biomass) for highly efficient electricity generation using Liquid Metal Electrode Solid Oxide Fuel Cells (LME SOFCs).…”
