A dual pressure Euler turbine (dpEt)is proposed to recover energy from a hydrogen membrane raffinate flow. A tradeoff study between using the shaft power to drive an electric generator or the system air compressor will be conducted. A two-stage dpEt nozzle and turbine rotor will be designed and fabricated. Tests will be conducted in an existing casing and high pressure nitrogen test system to verify performance. A full size dpEt and generator and hot gas test system will be designed to qualify the unit for a 500 kW fuel cell system.
