Jukka! Shame on you. Fuel cells in Teslas (ones that work, are practical and don't cost twice as much as the rest of the car) are a pipe dream. If you haven't already, I suggest you read... http://planetforlife.com/h2/h2conclude.html ...and the associated pages (the link is to the conclusion). It is a bit dated now (2004) but the laws of physics and chemistry have not changed much, so the conclusion is still valid. H2 fuel cells as a replacement for fossil fuelled ICEs (or battery electric drive trains for that matter) in personal transport vehicles do not work and probably never will. For a host of reasons. Amen.
