New fuel cell could enable electric aviation

If airlines wanted to use a fuel that had to be heated or cooled they could use alcohol fuels (need just a little heat to not freeze high up in the sky) or liquid methane, both of which are much easier to synthesize than the Fischer-Tropsch Kerosine that sustainable aviation fuels are stuck on now.
Meanwhile this thing basically sprays lye out the back of the plane the same way a bird sprays urea, I'd hate to be past the runway when these are taking off.
