摘要： An electrochemical fuel cell stack includes a plurality of fuel cell assemblies interposed between a pair of end plate assemblies. The mechanism for securing the stack in its compressed, assembled state includes at least one compression band which circumscribes the end plate assemblies and interposed fuel cell assemblies of the stack. At least one of the end plate assemblies is sufficiently thin so as to deflect under the compressive force if the at least one end plate assembly is supported only at a peripheral edge portion thereof. Preferably, at least one of the end plate assemblies comprises a resilient member which cooperates with each compression band to urge the first end plate assembly toward the second end plate assembly, thereby applying compressive force to the fuel cell assemblies to promote sealing and electrical contact between the layers forming the fuel cell stack.

摘要： A system for mooring a ship-shape floating production system using a riser tensioned by a weight type motion compensation system. The riser is attached to the ship by a rocking beam that has a weight attached at one end of the beam to balance the vertical load component of the riser attached at the other end of the beam. A rocker arrangement is used whereby the beam support point moves to compensate for the inertial forces of the weight caused by the vertical accelerations of the tanker. Thus the high load fluctuations and hence poor riser fatigue life usually associated with weight type motion compensators is minimized. A gear arrangement is used to transmit horizontal loads. The overall arrangement provides a totally self-contained motion compensation and riser handling system that requires minimal ship modifications and is independent of significant self-induced wave loading.

摘要： There is disclosed a type of riser to connect subsea hydrocarbon production equipment to a floating storage, process or control facility which combines the advantages of integral and non-integral risers previously used. This is achieved by a locking mechanism which allows the individual tubes to be freed once each section of riser is added, and a subsea remotely operated connector that allows individual tubing to be released. Improvements in the design of collet connectors are also disclosed. There is also disclosed a guidelineless method of connecting risers or other equipment to subsea installations. The method uses a cone on the subsea equipment and a guideframe on the riser. The guideframe aligns itself with the subsea cone prior to the riser being connected. As the riser is drawn to the subsea mandrel the guideframe aligns the riser connector with the mandrel. A still further embodiment disclosed herein is a flexjoint consisting of a series of flexjoints in an outer case with a high pressure tube inside. Internal tubes are fixed at either end of the assembly to the outer case.

摘要： An improved membrane electrode assembly (“MEA”) comprises coextensive ion exchange membrane and electrode layers and a resilient fluid impermeable integral seal comprising a sealant material impregnated into the porous electrode layers in the sealing regions. The integral seal preferably circumscribes the electrochemically active area of the MEA. The integral seal preferably also extends laterally beyond the edge of the MEA. An integral seal may also be provided around any openings, such as external manifold openings formed outside the MEA. Preferably, the uncured sealant material is a flow processable elastomer applied using an injection molding process. In preferred embodiments the seal has a plurality of spaced, parallel raised ribs with cross-ribs extending therebetween at spaced intervals. The raised ribs and cross-ribs provide compartmentalized seals that provide improved protection against fluid leaks.

摘要： An improved membrane electrode assembly ("MEA") comprises coextensive ion exchange membrane and electrode layers and a resilient fluid impermeable integral seal made by impregnating a sealing material into the porous electrode layers in the sealing regions. The integral seal preferably circumscribes the electrochemically active area of the MEA. In addition, the integral seal preferably extends laterally beyond the edge of the MEA, enveloping the peripheral region including the side edge of the MEA. The uncured sealant material is preferably a flow processable elastomer that is applied to the MEA using a vacuum injection molding process. In preferred embodiments, the seal has a plurality of spaced, parallel raised ribs with cross-ribs extending therebetween at spaced intervals. The parallel raised ribs and cross-ribs provide compartmentalized seals that provide improved protection against fluid leaks.

摘要： A subsea caisson or silo for housing wellhead equipment and methods of installing it is disclosed. A caisson which is sized to receive equipment that is to remain subsea has a closed top and open bottom. The caisson is lowered to the seabed and hydrostatic pressure in combination with a suction jet is used to remove the internal soil. If required the caisson may include a conical suction head located near the bottom of the caisson wall and rotatable cutting heads are fixed to its lower surface so as to cut into sea bottom material of hard consistency.

摘要： In an improved electrochemical fuel cell assembly, a reactant flow path extends substantially linearly across the electrochemically active area of an electrode. The electrode has an in-plane nonuniform structure in its electrochemically active area as the active area is traversed in the direction of the substantially linear reactant flow path. Embodiments in which the structure of the fuel cell electrode varies substantially symmetrically along the reactant flow path are particularly preferred in fuel cells in which the flow direction of a reactant is periodically reversed.

摘要： A flow field plate assembly for an electrochemical fuel cell comprises two flow field plates, each of which has channels formed on an inner surface of the plate. The plates are alignable with and engage each other such that their cooperating inner surfaces form at least one inner coolant fluid channel. The coolant channel has an essentially constant cross-sectional perimeter along its length, which is defined by the perimeters of the channels of the two plates and their difference in width at the cooperating plate surfaces. Additionally, a flow field plate assembly, which comprises a corrugated flow field plate and a staggered flow field plate, is structurally stronger under compressive load during the fuel cell operation.
