Does this exist as a consumer product yet?
This is a research paper, so it's gonna be at least a couple of years until ot could be seen in products. However the battery uses hydrogen, it's effectively an alternative to fuel cells, so the use case would be in vehicles rather than yout phone. That being said, hydrogen fuel infrastructure is almost non-existent right now.
Others downvote you and say "read the article", but not giving arguments.
I read the article and it is not clear what is the advantage... looks like less pressure is needed than other types of hidrogen cells, but there are no details.
I agree with you, don't hold your breath for this. All details would be in first sentence if there was any chance of this becoming reality.
The advantages are, every part of the device can be easily recycled, and the parts to make the charge-holding portion of the battery are less damaging to acquire than in li-ion
