Hydrogen motors are made by who?
I didn’t know hydrogens had a motor
A hydrogen fuel cell makes electricity which then drives an electric motor. Toyota and others makes such cars.
I wonder what you mean by that. If you mean engines here is the answer. https://en.wikipedia.org/wiki/Hydrogen_internal_combustion_engine_vehicle If you mean a motor there is no such thing, they run on electricity, and can be made by many companies. Try again.
