Abstract

This paper discusses a new concept for Direct Carbon Fuel Cells (DCFCs) developed in the University of St Andrews. DCFCs use solid carbon as a fuel directly, which has a high energy density compared with other energy carriers. The St Andrews/DSTL DCFC utilises a combination of the technologies of Solid Oxide Fuel Cell and Molten Carbonate Fuel Cell (MCFC) technologies whereas most earlier DCFCs were based solely on MCFC technology. A solid oxide electrolyte is employed to separate the cathode and anode compartments while a molten carbonate electrolyte is also present in the anode compartment to enhance the anode reactions. This new concept avoids the need for CO₂ circulation and the protection of the cathode from molten carbonate. Fuel cell testing has been carried out using a Super-S carbon fuel, a yttria-stablilized zirconia (YSZ) electrolyte, NiO/YSZ cermet anode, (La_0.8Sr_0.2) _0.95MnO₃ cathode, and a eutectic molten carbonate mixture (lithium carbonate and potassium carbonate). Promising fuel cell performances have been shown in the temperature range of 550-900°C. The OCV and maximum output at 900°C were 1.24 V and 6.9 mW cm^-2.
