  • Publication number: 20150093673
    Abstract: A fuel cell stack assembly is disclosed that includes a porous member disposed within a flow path for a reactant. A fluid collection member is provided within the flow path adjacent to and in fluid communication with the porous member. The porous member and the fluid collection member cooperate to collect liquid water from the reactant flowing in the flow path, wherein the collected liquid water may be drained from the fluid collection member.
    Type: Application

  • Patent number: 6390078
    Abstract: A two stage exhaust gas recirculation (EGR) valve delivers a wide range of EGR flow while operating with reduced valve actuating forces allowing use of a reduced cost actuator such as a solenoid with smaller sized coil and armature. An attached valve body mounts concentric dual pintle valves including a larger first valve, which engages a valve seat in the valve body to control exhaust gas flow between inlet and outlet openings and a smaller second valve positioned inside the first valve and engaging a second valve seat in the head of the first valve. The second valve controls a low flow passage inside the first valve. The solenoid armature engages only the smaller second valve during a first stage of its stroke so that the smaller valve is opened first and flow control is maintained in a low flow range. Exhaust and intake differential pressures acting on the second valve are overcome by a smaller armature force because of the smaller area of the second valve.
