(4 Comments)Any hydrogen usage (fuel cell or other) needs great care to make sure that there won't be a fuel leak and explosion. In an very well engineered fuel cell vehicle, this is unlikely, but in trivial applications where the engineering is more marginal accidents are not only likely to happen, they are certain.
50 years ago I scattered glass throughout a laboratory when I caused a hydrogen explosion from a poorly purged furnace. I had been poorly instructed, but the education I got from the explosion is still strong. Fortunately, I was the only one present and looking away from the explosion.
Hydrogen toys will have to carry a rather large product liability, as I see it.
