Unused fuel in a fuel cell is recirculated in the anode loop and combined with fresh fuel using an electromagnetically driven pump. The pump includes a magnetic rotor mounted inside a conduit of nonmagnetic material that recirculates the fuel, and a plurality of electric stator coils disposed around the outside of the conduit. The stator coils are powered by either a AC or pulse train signal produced by a controller, and generate synchronous electromagnetic forces that spin rotor to force the gas through the recirculation loop.
