Sentence examples for open ratios from inspiring English sources

The objective of this study is to make a systematic experimental investigation of DMFC performance in the presence of current collectors with different free open ratios and total perimeter lengths of the free openings.

Current collectors with 5 × 5, 7 × 7, and 10 × 10 hole arrangements under different total free open ratios of 30%, 40 %, 50, and 60% and investigated.

The characterization was performed by measuring polarization curves of the fuel cell using current collectors with different open ratios on anode and cathode.

The design parameters that were investigated include the open ratios of the perforated polytetrafluoroethylene (PTFE) sheet, and the anode gas diffusion layers (GDL) and the cathode filters.

Simulation results show that for the air-breathing PEM fuel cell operated at 353 K and one standard atmosphere pressure, when the anode channel ratio is fixed at 10%, the optimum cathode open ratios are very similar for the cell operated at voltages of 0.7 and 0.4 V, namely, 49.8% for 0.7 V and 49.5% for 0.4 V.

In contrast, among the 100 arrayed markers with the lowest log2 open ratios, only eight overlapped an island, 19 overlapped a single early replicating clone, and nine were within 50 kb of an island or clone.

In addition, a longer total perimeter of the free openings yields higher cell performance with the same free open ratio of the current collectors.

Pipe open ratio,.

The results show that the total free open ratio can significantly affect cell performance; they also show that decreasing the total free open ratio decreases cell performance, and increasing the total free open ratio increases cell performance.

The combination of current collectors using a relatively higher anode open ratio and inversely a lower cathode open ratio helps enhance the cell performance.

The total number of holes on the perimeter presents greater effects than the free open ratio.
