* Low Production Volumes: Hydrogen fuel cell vehicle (FCV) production globally is extremely low compared to gasoline or electric vehicles. Specific US manufacturing numbers are rarely tracked separately and publicly released by manufacturers.
* Limited Manufacturing in the US: While some components might be made in the US, complete assembly of hydrogen cars for the US market is not a significant manufacturing activity. Most hydrogen cars sold in the US are imported.
Therefore, it's impossible to give a precise answer to your question. The number is likely very small, in the low hundreds or possibly thousands at most, depending on how you define "made in the US" (e.g., final assembly versus component production).
