This fuel cell system is "open breathing," as the oxygen ust enters from the outside into the spaces inbetween the plates. We got computer fans to increase air flow to the cell.

The hydrogen enters through the tube seen in the picture.

Nice close-ups by the way

Well i know it enters through the tube, but what I meant is how does it flow from plate to plate?

Connor can you get a picture up of the PEM? Do you know what brand PEM they use? I know Nafion is basically the best out there right now.
