A rotor and stator assembly is positioned within the housing radially outside of the distribution member. A toothed ring is interposed between the distribution rotor and the rotor and stator assembly. The toothed ring and the rotor and stator assembly define a gas ring therebetween. A reactant gas supply is fluidly coupled with the gas ring.
