I would assume that future fuel cell powered cars for general market consumption would not require onboard hydrogen to be stored at 10,000 PSI ... as was the case in the experimental Equinox! I wouldn't trust that much pressure around me noway, nowhere, nohow. However, I'm sure advanced research is going on to eliminate the need for these kind of storage pressures in future vehicles that might be powered by fuel cells.
From what I read, I guess that it's REALLY DIFFICULT to find a way to store energy for use in a vehicle that equals the inherent energy stored in liquid gasoline. Mother Earth seems to have pulled off a real feat by creating raw petroleum packed with so much energy ... as she is proned to do in a lot of things she does/did.
