摘要： The present invention relates to a fuel cell system and to a method of operating such a system. More specifically, the present invention relates to the manner in which a fuel delivery system of a fuel cell system is operated in order to achieve practical advantages in terms of system operation. The fuel cell system of the invention comprises: a fuel cell assembly; a steam reformer for delivery of a fuel cell supply stream to the fuel cell assembly; a jet pump for delivery to the steam reformer of a gas stream comprising steam and a gaseous hydrocarbon fuel, the jet pump comprising a steam inlet, an inlet for the gaseous hydrocarbon fuel and an outlet for the gas stream; a steam generator for delivery of pressurised steam to the steam inlet of the jet pump; and a source of a gaseous hydrocarbon fuel for delivery of gaseous hydrocarbon fuel to the fuel inlet of the jet pump, wherein flow of steam through the jet pump is responsible for entrainment and flow of gaseous hydrocarbon fuel through the jet pump in order to generate a gas stream comprising steam and gaseous hydrocarbon fuel that is suitable for delivery to the steam reformer.

摘要： A fuel cell stack comprising multiple arrays of one or more fuel cells, each comprising an electrolyte layer, an anode layer and a cathode layer; gas separator plates between adjacent fuel cells; and oxidant gas distribution passages and fuel gas distribution passages between adjacent fuel cells; and gas separators opening to the cathode layers and the anode layers, respectively, of the fuel cells. The fuel cell arrays comprise at least first stage fuel cell arrays having associated first fuel gas distribution passages to receive fuel gas from one or more fuel gas supply manifolds and second stage fuel cell arrays having associated second fuel gas distribution passages which receive fuel exhaust from the fuel cells of the first stage fuel cell arrays. The second stage fuel cell arrays are interleaved in the stack between first stage fuel cell arrays to improve thermal gradients. Other interleaving arrangements are possible.
