Yes, KOH is very common and easy to get. But here KOH is not the media to provide hydrogen. It’s a media to transport the charged ion or electron from anode to cathode, which just play the role as electrolyte. This method is not the main stream in current fuel cell.

But I doubt if its efficiency is really as good as tranditional electrode. Why they didn’t provide the efficiency data to confirm their work?

The oven cleaner + soda can trick is well known to all of those making hydrogen gas… it is even the basis for some of the “kits” you can buy online.

KOH is a strong base … it’s going to react with lots of things. I’m pretty sure the folks at AFC Energy are aware of this.

Mix aluminium + oven cleaner, you get fire… it does spit out a bunch of Hydrogen though…
