[ES] En este artículo se presenta una alternativa para la generación de energía eléctrica a partir de carbón mineral. El proyecto de la RFCS “Efficient conversion of coal to electricity: direct coal fuel cells (DCFC)” está actualmente investigando las ventajas asociadas a la tecnología. A saber: una alta eficiencia energética y muy bajas emisiones de contaminantes. En el último informe del proyecto se muestra cómo las características de los carbones utilizados son una clave en el comportamiento y la durabilidad de la pila de combustible. En principio, son preferibles los carbones con alta reactividad y bajo contenido en cenizas. Por otro lado, la adición de ciertos catalizadores puede ser importante para favorecer la gasificación in situ de carbono. Actualmente, el trabajo se centra el escalado y el desarrollo de los sistemas de sellado, interconexiones y alimentación de combustible.
[EN] An alternative for electrical energy generation from coal is presented in this article. The RFCS project “Efficient conversion of coal to electricity: direct coal fuel cells (DCFC)” is currently investigating the advantages associated to the technology. To wit: a high energetic efficiency and very low emissions of pollutants. In the midterm report of the project it is shown how the characteristics of the coals used are a key in the behavior and durability of the cell. It seems that coals with high reactivity and low ash content are desirable. Furthermore, the addition of certain catalysts may be important to promote in situ gasification of carbon. Currently the work is centered in the upscaling and developments on sealing, interconnections and fuel feeding systems.
The authors would like to acknowledge financial support from the European project “Efficient Conversion of Coal to Electricity – Direct Coal Fuel Cells”, which is funded by the Research Fund for Coal & Steel (RFC-PR-10007).
