"Hydrogen Fuel Cell" is just a battery; and it's an inefficient battery, far less efficient than the typical Lithium battery you find in a Tesla.
The advantage to a HFC is you can fill up the tank with liquid hydrogen (just like filling up a gas tank), but the disadvantage is hydrogen is made by running LOTS of electricity through distilled water; this breaks the water molecules into their component Hydrogen and Oxygen atoms. You need to produce a lot of electricity to produce the hydrogen, then use a lot more electricity to cool it enough that it condenses to liquid. When put into a tank, that liquid hydrogen produces a moderate amount of electricity in a HFC.
You are confusing amperage with voltage. Both can produce hydrogen through electrolysis one is a measure of the rate of waste and the other is a difference in potential that accomplishes the same thing at a much lower rate of waste. I reject your opinion
