Load cycles  were applied to the PEFC, and the dynamic voltages were monitored. During the experiments  shown in jump-run.zip, seven attributes of operating conditions were varied. The experimental setup is specified in detail by Shi [1]. The data files are according to section 5.1 in [1]. The data files in the path jump-run/ contain terms like 0.x-yy, where 0.x is the upper level of the load ramp, starting at 0.2 A cm-2, yy is a numbering of the set of operating conditions, listed in the file 'ramp-up-Experimental setup of DoE methode.pdf'. The parameters A to G are according to Table 5-1 in [1].&#xd;
The files in the path ramp-up/ contain experiments operated under stepwise increasing electrical load as specified in the file 'jump-dynamic-Experimental setup of dynamic DoE methode.pdf'. The parameters A to G are according to Table 6-1 in [1].&#xd;
Data with constant operating conditions and different ramp characteristics are published by Froning and et al.
