It would be nice to see some actual working fuel cells, I mean how long have they been dangling those things in front of us?! Enhough with the R&D, show me some working consumer product!!

at least not as well as batteries, given the same total weight/volume yet. Probably won't in the near future since they require either high pressure hydrogen storage, or highly toxic chemicals (like methanol) storage.
They keep popping up at tech symposiums because the tech-illiterate media hasn't figured out the scam yet (after almost 10 years!) and it's still good for some free press, even here.
If it's safe enough for the UK powergrid, then it's safe enough for me. Anyways, it just needs to be strong enough that any non-fatal collision while I'm carrying it doesn't rupture the thing. If the plane/car/skateboard I'm on wipes out with enough force to terminate me, then I'm not really fussed about any leakage, coz I'll be dead.
Most cars had a good litre or so of methanol in their coolant until it was largely replaced by ethylene glycol some years ago. It's still in screenwash and in methylated spirits.
You need to consume a reasonable amount to injure yourself (don't try it!). Most methanol poisoning is from deliberate or accidental misuse as an intoxicant.
The electrolyte in a lot of conventional batteries is potassium hydroxide, which is much nastier.

Potassium hydroxide nastier than methanol? Maybe if you injected it, but methanol is toxic by inhalation and skin absorption (and ingestion, obviously) as well as being highly flammable. Lethal oral dose for mammals seems to be a few grams per kilo, but you'd see nasty effects with much less - so no, don't try consuming any amount, reasonable or not. I would be very surprised to find significant amounts of methanol in any screenwash on sale in the UK, got a reference?

Yes, potassium hyroxide is a lot nastier than methanol. From the same site : http://ptcl.chem.ox.ac.uk/~hmc/hsci/chemicals/potassium_hydroxide.html
Methanol is a dangerous chemical, and potassium hydroxide is a very dangerous chemical. Methanol may cause damage if you're not careful, potassium hydroxide WILL cause damage if you're not careful!
