METHOD FOR CONTROLLING DEPOSITS IN THE FUEL REFORMER OF A FUEL CELL SYSTEM

摘要

A method for controlling the deposits in the fuel vaporizer of a fuel reformer used to prepare a liquid hydrocarbon for use as a fuel in a fuel cell which comprises introducing into the fuel vaporizer a liquid hydrocarbon containing an effective deposit controlling amount of a nitrogen-containing detergent additive and a fuel composition suitable for use in a fuel cell which comprises a liquid hydrocarbon having a boiling range at atmospheric pressure falling between about 77 degrees F (25 degrees C) and about 437 degrees F (225 degrees C), a total sulfur content of less than 3 ppm, and containing an effective deposit controlling amount of a nitrogen-containing detergent additive.
