As to individual passenger cars, the points raised have merit. However, with fleets and commercial operations, I think that the jury as to the use of hydrogen is still out, see the Riversimple topic ( http://myimiev.com/forum/viewtopic.php?f=12&t=3011 ) and the posts in that topic concerning Aberdeen and the Hykangoo, for instance. Obviously not all inclusive as there are also a number of bus operations elsewhere using or experimenting with hydrogen including ACTransit in California: http://www.actransit.org/environment/the-hyroad/
These seem to be successful at this point and the Riversimple car experiment is still pending.
