Getting fuel cells into planes (inside your gadgets, that is)

Following the news the other day that KDDI is planning to have fuel cells in its phones by 2007, Nikkei BP is carrying a (Japanese-only) article that claims, unsurprisingly, that fuel cell makers are starting to lobby governments to overcome a big stumbling block: the fact that you can't take methanol cartridges onto planes (or, theoretically, any form of public transport where "dangerous articles" are banned; so all of them,
then). It will supposedly take until 2007 to get the ban revoked (which may be where KDDI gets its target from), though international bodies should give the nod in 2005.
