Hydrogen vs. Battery Electric Cars

I am not anti-hydrogen per sé. I think if research is being done, there wille be more fueling-places, price will eventually come down (maybe not below gasoline but... is that necessary?)  Still I did come across some worrysome articles. These claim that hydrogen alway leaks through tanks. Not enough to cause  acute explosion- or fire hazard but it does rise up in the atmospere. Here i may deplede the Ozone-layer. Now, with100 FCEV's or even 10000 this won't be a problem. It might when a whole economy is driven by it.

Fuel cell technology is very elegant, in my opinion. But we really should look into the ozone-layer issue. We now have the technology to do this as  a few hundreds years ago we did not when we started with coals and other fossil fuels.

Another thing : Fuel cells use Platinum and/or Iridium as a katalyst to make it work. These are rare metals and these need to be mined. Many say that production of batteries needs depletion of minerals. And this is true. But the mining for Platinum may not be less invasive.
