A fuel cell system includes a fuel cell assembly that includes 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 for providing a flow of gaseous medium to the fuel cell assembly. The centrifugal blower system includes a series of blower units, 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 blower unit in the series of blower units with the axial inlet of at least one successive blower unit in the series of blower units.
