Re:fossil fuels for now (Score 1)

No way duude, the combustion engine does not have the same potential as a fuelcell when it comes to converting chemical energy to mechanical energy. Thats the real reason to use fuel cells, not to CO2 probelm. As today we make H2 mostly from natural gas or coal, depends on you are in US or EU, hehe, and CO2 is a by product as when we burn these fossile fuels. BUT we make much less NOx and SOx which are the real killer polution gases. Also copeing with a large local CO2 production is easier than from thousand small ones. And last it is not necessary to use platinum, paladium, ruthenium or rhodium as catalysts in fuelcells. It is possible to make bi, tri, metallic alloys with same catalystic effects, IN THEORY...
