How will fuel cells NOT cut down on CO2 emmissions? If they are using pure hydrogen, the only emmission will be H2O. You didn't read the article did you? This prototype uses Methanol, for safety purposes, but when mass production time comes the problem of safe hydrogen storage should be solved.
As for Hydrogen generation, yes, it will be generated by H20 which will cause more CO2 to be spit from the power plant, but may also be drilled from the earths crust, as in this Slashdot article.
