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 (14) which is , used in the feedstock to the reformer (13) is directed to at least a portion of the fuel cells (11) 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.
