Same stuff that comes out all the time -- put in oxygen and hydrocarbon fuel (gasoline), get out carbon dioxide and water. Lots of it. One reason that hydrogen is an attractive fuel is that the end product is simply water, without the CO2. The catalyst functions to adjust the small amounts of hydrocarbons (burn them to H2O and CO2), nitrogen oxides (reduce them to nitrogen) and carbon monoxide (oxidize to CO2). The reason we need an O2 sensor on the engine is that the mixture control must be very close in order for the ratios to come out right in the cat. converter. david
