FUEL CELL SYSTEM

摘要

A fuel cell produces electricity by reacting a higher carbon hydrocarbon fuel with steam in a steam pre-reformer, whose temperature does not exceed 500° C. A fuel stream is produced that includes hydrogen and not less than about 20% by volume methane, measured on a wet basis. The fuel stream and an oxidant are supplied to a high temperature fuel cell in which the methane is reformed. The fuel cell produces electricity by reacting the fuel stream at a fuel cell anode, and by reacting the oxidant at a fuel cell cathode.
