#2How is this not on the front page? If we have a low cost catalyst then Hydrogen Fuel cells become affordable and are well placed to disrupt how the world thinks about energy. This is an exciting time to be alive!

How do hydrogen fuel cells disrupt the world? The fuel for today's fuel cells is natural gas. How would these be any different?

Energy breakthrough exhaustion. There are just too many breathless press releases and articles and they mostly drift away to join the aggregate body of scientific knowledge.
Way outside my field here, but this one doesn't address cost of production, only cost of components. Platinum is about $12/kW with current technology fuel cells. In a quick googling I found a 1kW fuel cell for $6000. It is safe to assume the platinum cost is fiddling about the edges. Combine with the hunch that creating large structures out of carbon nanotubes with nickel nanoparticles arranged in a certain way isn't going to be free, and my interest ebbs quickly.
The good news of this article is that if we do somehow end up in a future where fuel cells are widely used, we will need not be constrained by the world supply of platinum… but that isn't front page news.

#5The biggest issue with fuel-cells is it will prolong the rein of hydrocarbon [natural gas], from which ~95% of hydrogen is extracted. Which everyone now knows is both dangerous and unsustainable.

Because some people believe fuel cells are better tech than batteries. It's not true of course, but that's where the belief comes from.
Batteries store energy. Fuel cells are solid state engines, not storage systems.

I thought the problem with hydrogen as a fuel was storage --- liquification requires cryogenic temperatures and is very energy inefficient, compressed gases require heavy storage vessels and has terrible energy density, infusing it into the surface metals has poor energy density and is problematic for other reasons... actually turning it into energy is pretty well understood; it's getting it to where it's needed that's not.
Or has something changed since I last looked at this?

#8While this is interesting, it doesn't change my opinion that the future is electric, not hydrogen fuel cell. Not only for the way hydrogen is extracted but the complexity of the technology. These set of blogs[0] are by a non-expert, but explain well why it's actually more complex than the ICE and inferior to electric.
Highly recommended reading for laymen like myself who want a view at the technology from a common sense standpoint.
My personal view outside of the needless complexity and lack of fueling stations, is that it's conveniently a way to ensure automakers keep us reliant on their expertise to repair and build these vehicles. Rather than the mechanical simplicity thus commodities that electrics are becoming.
As well, having China onboard with electrics ensures its future. It's mainly the Japanese and some US companies that want to push HFC. If electrics win out (and they more than likely will), everyone (including Apple) will be selling cars because it'll be mostly a software game.
I'm very much looking forward to the Tesla Model 3 reveal and putting down my preorder. Strangely enough it feels like this is going to be one of those breakthrough products for me. Alongside my Commodore did in 1986, 3dfx Voodoo card did in 1996, and the upcoming SteamVR (HTC Vive).
Great time to be alive.

#9I wonder if these new nanocatalysts are having an impact in organic chemistry in general. Anyone know?

Fuel cells aren't just about cars.
