About 2003 I installed a Stereo in a proto type “fuel cell” Jeep that Chrysler was working on, they used it at the CES show that year and many more.
It was not like those, these create electric from a chemical reaction to run the electric motors.
We heard a lot about the fuel cells then but I haven’t in years.
As for Hydrogen power vehicles a lot of companies have been working on them, also did a system for a Ford show vehicle that was going to be a normal motor, powered by Hydrogen, it was called the Model "U". The engineering feat is in getting hydrogen and a safe storage means.
Haven't heard much about them in years.
