Figures 5.2 and 5.3 demonstrate the results of a test of length 5000 s. Simulink
results for the cell voltage current characteristics and the corresponding stack
temperature are shown in Figure 12.16 and 12.17, respectively.
The integrated closed-loop SRFC system Simulink model is shown in
Figure 12.18. The closed-loop Simulink model was run for one complete day,
