We tested the fully assembled bipolar membrane flow cell and posted it to my friend Jeremy's channel. You can see the preliminary results here:

We got picowatts of power so far, which is similar to preliminary results at Prof. Daniel Sheehan's lab at U.C. San Diego with their devices. The result is quite repeatable. So far the device is unoptimized so we expect a factor of 2 or 4 more power from an optimized device. We'll add our final video for the competition in the morning, as well as some supplementary references.
