1. A fuel cell system comprising:
a solid oxide fuel cell assembly comprising a plurality of individual fuel cells, each fuel cell having an electrolyte medium, a cathode and an anode; and, at least one centrifugal blower system providing a flow of gaseous medium to the fuel cell assembly, the at least one centrifugal blower system comprising:
a series of blower units connected in series, each blower unit in the series comprising a casing, having an axial inlet and a radial outlet, an impeller disposed within the casing for drawing a gaseous medium at a first pressure in the axial inlet and expelling gaseous medium at a second higher pressure through the radial outlet, and a motor for driving the impeller; and,a duct connecting the radial outlet of at least one upstream blower unit in the series of blower units with the axial inlet of at least one successive downstream blower unit in the series of blower units.
