Fuel cell based torch

A Hydrogen Fuel Cell powers this torch (via). Called the Angstrom's A2, it gives out 24 hours of continuous light. The folks who make this product claim that it can be recharged in a couple of minutes as against hours for rechargable batteries used in conventional torches. The fine print is that it requires their proprietary "Refueling Station" and some hydrogen. No doubt a cool toy but the questions I want to ask is

1. Can I take on a plane?
2. What will it cost?
3. Where can I get Hydrogen? Not in the neighbourhood store for sure.
