Reading about GM's Billion-Dollar Bet there are several points of good news about fuel cells:

First off - Fuels cells are no longer found only in German research labs (and of course as we're proud to mention at Risø labs, the danish research institution founded by Niels Bohr and at the forefront of moderne energy research (wind power and fuels cells)).

Secondly, products ARE beginning to appear. As per the usual technolgy adoption path, fuels cells are being tested for real applications, first where price does not matter as much as the inherent benefits of fuels cells : The highest energy density available.
Elsewhere (link TBA) it has been reported that battery sized fuel cells are reaching the market right about now, for remote hard-to-service devices where chemical batteries or other power sources are less than practical.

Now that some of the more radical computer controlled hybrid approaches to power are being to appear on non-weird vehicles, maybe the fuel could actually be next.
