The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.4 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00005 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.07 SJR: 0.198 SNIP: 0.48 CiteScore™:: 1.1 H-Index: 20

RESUMO

Direct carbon fuel cells in which carbon is electrochemically gasified into carbon monoxide offer large thermodynamic advantages. Because the entropy change in this reaction is positive, the theoretical reversible efficiency of a direct carbon fuel cell can be greater than 100%. It means that heat is subtracted from the environment and directly converted into electric power. Hence in contrast with general belief heat can be converted into power with an efficiency greater than the Carnot efficiency. Also the enthalpy of the gasification reaction is directly converted into power whereas in present gasifiers this enthalpy is converted into heat.
These are the driving forces for developing direct carbon fuel cells. Molten carbonate offers good possibilities for the construction of these fuel cell but also YSZ the electrolyte of a SOFC is proposed. Possibly a combination of both in which molten carbonate provides additional reaction paths is possible as well.
On short term the prospects of integrating an MCFC or SOFC with a molten carbonate gasifier looks very promising.
