摘要:
A fuel cell assembly includes a membrane electrode assembly (MEA) stack has a plurality of stacked planar membranes. The MEA stack further includes gas passageways arranged so that anode and cathode gases flow perpendicular to the planar membranes between a first side and a second side of the fuel cell assembly. Anode gas inlet and outlet ports and cathode gas inlet and outlet ports are disposed on the first side of the fuel cell assembly and coupled to the gas passageways of the MEA stack.

A fuel cell assembly includes first and second compression members at first and second ends of the fuel cell assembly. A membrane electrode assembly (MEA) stack is disposed between the compression members. The MEA stack includes a fluid flow passage that allows gases to flow between the first and second ends of the fuel cell assembly. A fastening member connecting the first and second compression members and is disposed within the fluid flow passage of the MEA stack.

A fuel cell assembly includes first and second compression members. Two or more membrane electrode assembly (MEA) stacks are disposed between the compression members, each MEA stack having a positive and negative end. A first current collector is electrically coupled to a positive end of a first stack of the MEA stacks. A second current collector is electrically coupled to a negative end of a second stack of the MEA stacks. A current shunt is disposed between the compression members and electrically couples the MEA stacks.

A fuel cell assembly includes two or more plate assemblies stacked together. Each plate assembly includes a membrane electrode assembly (MEA) sandwiched between an anode plate and a cathode plate. At least one of the anode plate and the cathode plate has a first flow field on a side facing the MEA and a second flow field on a side facing away from the MEA. The first flow field is of a first uniform depth, and the second flow field is of a second uniform depth. In one configuration, the first and second uniform depths are the same.

A high temperature resistant flotation core and a high temperature resistant oil containment boom which allows for the in-situ burning of spilled or leaked oil during offshore oil spill cleanup operations are disclosed. The boom can also be used for precautionary fire containment during non-burn oil spill cleanups and can be easily recovered and redeployed.

An efficient, economical, compact diesel particulate filter comprising a casing radially filled with a bundle of tubes comprising woven, braided, or knitted inorganic yarn, wherein each tube is at least about twice the length of the bundle, and is folded at one end to prevent exhaust from traveling through the hollow of the tube without passing through its wall.
摘要:
A method is disclosed for making an insulated splice or terminal, the method including the steps of adhering an elongated layer of non-conductive material to an elongated layer of electrically conductive material so as to form a composite supply strip; severing a predetermined length of said supply strip from the remaining supply of said strip; and crimping said length about the elements to be joined until said electrically conductive material is in electrical contact with the said elements and so that the non-conductive material forms an outer insulated layer enclosing said splice or at least a portion of said terminal. In a preferred method of the instant invention, a further step of causing the non-conductive material of the splice to "flow" is employed whereby a resultant sealed splice is produced which is impervious to moisture and other contaminants. Novel composite supply strips for use in the aforedescribed method are also disclosed as well as a novel die for use in an automatic splice producing machine which includes means for forming such splices from a continuous supply roll and optionally means for forming the composite supply strip.
