Single-cell genomics is heavily dependent on increasing the copies of DNA found in the cell so that there is enough statistical power for accurate sequencing. This has led to the development of strategies for whole genome amplification (WGA). Currently, WGA strategies can be grouped into three categories: Controlled priming and PCR amplification: Adapter-Linker PCR WGA

The single cell test results show good agreement with the model and stack results at lower concentrations (0.7–0.9 M) for 0.20 A⋅cm −2 current density ( Fig. 7c). Generally, it can be observed that in a stack there is always a small difference between the individual cell voltages.
Although the single cell test conditions are arranged according to the short stack results for the comparison, the results from the single cell test rig are utilized for three methanol concentrations (0.5 M, 1 M and 1.5 M) and three CFRs (10, 20 and 30 ml⋅cm−2 ·min −1) to investigate the performance characteristics of the single cell.
Single cell testing of the DMFC is performed in a cell test rig for various current density (i), operating temperature (T A ), CFR (V C) and methanol concentration (C MeOH) values. In contrast to the short stack test rig, the cell temperature is an input parameter and the cell temperature is maintained with heating.
