August 2 NovascienceNOW 8 PM. (this is Seattle area PBS station time, may vary for your location) will discuss other things besides fuel cells (probably more interesting) and im afraid the discussion on them will be a lot of stuff most of us already know, but then again it might be informative, or spin, or wishful thinking not born of even an inkling of fact. YMMV
If it's not on in your area, it is available online at http://www.pbs.org/wgbh/nova/sciencenow/watch/ The Fuel Cells segment runs about 13½ minutes.
