When I have read articles on this subject, they mention a sort of chemical reactor that extracts hydrogen from whatever fuel is being used. The hydrogen runs the fuel cell and then there's all this muck you get from what's left. My big question is Wouldn't that be just as bad or worse than the smoke from conventional combustion? Assuming the chemical reactor extracts hydrogen, there is still sulphur, carbon and no telling what else that was part of the Diesel fuel. The same statements apply to gasoline and alcohols. What do you have left after extracting the hydrogen and what could you do with it? There have been discussions at least in the press of using various petroleum products and a chemical reactor device to extract hydrogen to transition from petroleum-based fueling systems to some method of directly using, storing and transporting hydrogen in the future.
