The hydrogen tank is....

uh... is....

uh...

I don't see it either. It *was* next to the fuel cell, or "up" in referance to the picture. The tank is smaller than the fuel cell.

There is no oxygen tank. The fan, however, is there to circulate oxygen rich air over the fuel cell to keep the hydrogen-oxygen reaction going.

I never really thought about circulating air (and oxygen) around a fuel cell until the fuel cell students told me about it - which makes sence. I guess that fan just about doubles the power output of our fuel cell.

It's a really amazing chance to play with something that most of us have never seen before.
