Evaluation of raw coals as fuels for direct carbon fuel cells

As a promising high-temperature fuel cell, the direct carbon fuel cell (DCFC) has a much higher efficiency and lower emissions compared with conventional coal-fired power plants. In the present DCFC system, four Australian coals from Central Queensland are successfully tested at 600–800 °C. The electrochemical performances of these coals are highly dependent on their intrinsic properties, such as chemical composition, surface area,...
