  • Patent number: 11092289
    Abstract: A fluid storage and pressurizing assembly includes a storage receptacle and a pump assembly. The storage receptacle includes an inner vessel defining a cryogen space for storing a fluid at a storage pressure and a cryogenic temperature, an outer vessel surrounding the inner vessel, and an insulated space between the inner vessel and the outer vessel, and a pump assembly. The pump assembly includes a pump immersed in the cryogen space having an inlet for receiving a quantity of fluid from the cryogen space, and an outlet for delivering the fluid therefrom. The pump assembly further includes a pump drive unit for driving the immersed pump, the pump drive unit being at least partially disposed within a space defined by the storage receptacle.

  • Patent number: 9240598
    Abstract: In solid polymer fuel cells employing framed membrane electrode assemblies, a conventional anode compliant seal is employed in combination with a cathode non-compliant seal to provide for a thinner fuel cell design, particularly in the context of a fuel cell stack. This approach is particularly suitable for fuel cells operating at low pressure.
