We investigated the relationship between cell voltage and the differential pressure through cathode channel, with the three different cells which have different channel-pattern on each. In the cases of straight 1-channel and serpentine 1-channel, the cell voltage was well synchronized with differential pressure. In case of parallel 3-channel, however, the synchronization did not occurred clearly. To evaluate the relationship quantitatively, we calculated the cross correlation between cell voltage and differential pressure. It figured out that the straight 1-channel and serpentine 1-channel cells showed a good correlation of -0.5 and that parallel 3-channel indicated a weak correlation of -0.3 under flooding condition. We considered the reason to give the correlation difference between different channel-pattern cells with a visualization study.
