Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Studies from National Cheng Kung University Add New Findings in the Area of Energy (Enhancement of Proton Exchange Membrane Fuel Cell Net Electric Power and Methanol-reforming Performance By Vein Channel Carved Into the Reactor Plate)

Article Description
A prospective small power system that uses fuel from a small reactor to turn methanol into hydrogen is a proton exchange membrane (PEM) fuel cell (FC). This article examines the fuel conversion ability of the small methanol steam reformer (MSR) creating different vein channels with varying widths and angles on the reactor plate and PEMFC net electric power at various heated temperatures. For each channel, the catalyst quantity remains the same. The maximum hydrogen yield is 92.44%, methanol conversion 0.01187 kmole ⋅ m −3, and cell net electric power 133.86 W. The augmentation of hydrogen yield and methanol conversion from the innovative SR reactor by the vein channel of width 1.25 mm and angle 120° achieves 84.32% and 29.52% compared to the parallel-channel SR reactor under T wall of 250 °C. The novel SR reactor, having a vein channel with a width of 1.5 mm and an angle of 90°, acquires 29.09% compared to the parallel-channel SR reactor in PEM fuel cell net electric power under T wall of 250 °C, allowing low CO exhaust. The findings show that the novel SR reactor with a venous channel enhances the net electrical energy conversion of MSR and PEM fuel cells.
