Airbus is experimenting with fuel cells for airliners; I believe the idea is to use the fuel cells for cruising and use gas turbines when more power is required.[0] Joby Aviation (the air taxi developer) also bought a company that's been working on a hydrogen fuel cell light aircraft. The power density of fuel cells density would make VTOL air taxis a whole lot more plausible (though you've still got a distinctly nontrivial hydrogen storage problem). [1] There's another startup called HyPoint working on fuel cells specifically for aircraft [2], though they haven't announced a whole lot recently.
