It likely uses liquid hydrogen for fuel which can be difficult to come by as there aren't a lot of fuel stations that have that available. I found this video interesting and informative and it goes over some of the pros and cons of owning a hydrogen powered car - https://youtu.be/rtZQLUtckS4

So fuel cell cars other than one exception that I am aware of only use compressed hydrogen not liquid. Dealing with compressed hydrogen is difficult but manageable, dealing with liquid hydrogen is extremely difficult.
