Reuters reports that GM's hydrogen fuel cell cars face cost and design challenges that mean commercial production is about ten years away. Interviewed at the Ninth Grove Fuel Cell Symposium in London, Matthew Fronk, GM chief engineer for fuel cell systems, cited issues with performance, cost and durability. (I guess that means that they've got styling covered.)

Major issues also remain in the areas of hydrogen storage and distribution infrastructure, and the net cost of producing power from fuel cells.

So it looks like hybrids and clean diesels will be the automakers' focus for the next decade or so.
