The results so far, show qualitative agreement with previous measurements done by MRI and NI, but the resolution is much higher with micro-CT, so many more details can be observed. Water was observed emerging as water droplets on the surface of the diffusion layer. The droplet grew in size, and eventually detached into the flow channels. Drops in the flow channels were found to distort from the expected circular shape before they start to move. Some deviation in the shape of water droplets is observed, when compared to predictions from the modeling literature. This is believed to be due to the role of the channel side walls, as well as possible non-uniformities in the flow channel surface.
