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: 0.5 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.8 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: 0.2 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: 0.00018 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: 0.11 SJR: 0.286 SNIP: 1.032 CiteScore™:: 1.6 H-Index: 10

SINOPSIS

A liquid-feed direct methanol fuel cell (DMFC) is considered a promising choice of next-generation primary or auxiliary power devices. In this study, a DMFC with a transparent window was designed to investigate the two-phase flow phenomenon in anode interdigitated channels. With the aid of visualization technology, the effect of the two-phase flow behaviors coupled with chemical reactions on the performance of the DMFC under different current densities, methanol flow rates, and cell temperatures was studied. Results indicated the gradual increase in the number and size of bubbles with the increase of current density. High methanol flow rate could promote the movement of the gas bubbles. Fine bubble flow was the typical two-phase flow in outlet channels, and slug flow exists in outlet manifold. Gas quality, average bubble size, and gas columns increased with cell temperature. Moreover, the performance of the DMFC was promoted. Cell temperature had a significant effect on cell performance. By contrast, the effect of mass transfer deterioration caused by the CO2 bubbles could be ignored.
