A method of commencing operation of a fuel cell system which includes a fuel reformer is provided. During a start-up period, the same fuel which is used in the feedstock to the reformer is directed to at least a portion of the fuel cells in the system. These fuel cells provide output power by direct oxidation of the fuel, at least until the reformer is operational, producing a hydrogen-containing gas stream suitable for the fuel cells. Thus, useful output power can be obtained from the system without the delay typically associated with start-up of the reformer.

1. A method of commencing operation of a fuel cell system, said system comprising a plurality of solid polymer fuel cells, a supply of fuel, and a fuel processing subsystem comprising a reformer which processes a feedstock comprising said fuel to produce a hydrogen-containing gas stream, said method comprising:directing a starting fluid stream comprising said fuel to at least a first portion of said plurality of solid polymer fuel cells during a start-up period, whereby said first portion provides output power during said start-up period; and directing said hydrogen-containing gas stream from said fuel processing subsystem to at least a second portion of said plurality of solid polymer fuel cells after said start-up period, whereby said second portion provides output power after said start-up period.
