Abstract: Disclosed is a unitized electrochemical cell sub-assembly having a first separator plate and a second separator plate that each has a first surface. A recess is located in at least one of the first surfaces to define a chamber adjacent the periphery of the plates when the plates face each other. A membrane electrode assembly (MEA) comprising an ion exchange membrane and a pair of gas diffusion layers is disposed on and between each of the first surfaces between the two plates when the plates face each other so that the peripheral edge of the ion exchange membrane is located within the chamber. Also located in the chamber is a non-conductive sealant polymer that seals and joins the first and second plates to each other, and that seals and joins the first and second plates to the edge of the ion exchange membrane. Also disclosed is a fabrication method for making the unitized electrochemical cell sub-assembly.

Abstract: Trunking with port aggregation for fabric ports in a Fiber Channel (FC) fabric and attached devices is described. In some examples, a method of establishing a connection between a node and the FC fabric includes: negotiating a first link between a first trunking node port in the node with a first trunking fabric port in the FC fabric; creating a trunking port channel with the first link as a first member, the trunking port channel supporting a plurality of virtual fabrics; logging in a logical interface for each of the plurality of virtual fabrics to the FC fabric over the trunking port channel; negotiating a second link between a second trunking node port in the node and a second trunking fabric port in the FC fabric; and adding the second link to the trunking port channel as a second member aggregated with the first member.

Abstract: There is provided a process for sealing a coolant plate to an adjacent bi-polar plate or coolant plate in an electrochemical cell. The first coolant plate comprises at least one mating region for mating with a complementary region on the adjacent plate, the adjacent plate is a second coolant plate or a bipolar plate of the electrochemical cell, and the first coolant plate and the adjacent plate each comprise a polymer and conductive filler. The process comprises the step of welding the mating region to the complementary region to create a seal formed by the polymer at the mating region and the complementary region. Welding may be done using resistance welding or vibration welding processes.

Abstract: N_Ports and F_Ports are provided with logic allowing designation of multiple virtual interfaces on a single host bus adaptor or other Fibre Channel interface, one virtual interface for each VSAN operating on the node interface. Node ports with this additional functionality are referred to as trunking N_Ports or TN_Ports.

This port design also includes logic for communicating with a peer fabric port to initialize and modify the configuration of the virtual interfaces on the TN_Port. A corresponding functional design and communication logic is provided for fabric ports, referred to herein as trunking F_Ports or TF_Ports.

Abstract: Methods and devices are provided for non-disruptive monitoring of network traffic through one or more ports of a Fibre Channel network device. Preferred embodiments of the invention are used in conjunction with the switched port analyzer (“SPAN”) and/or remote SPAN (“RSPAN”) features. SPAN mode operation allows traffic through any Fibre Channel interface of a network device to be replicated and delivered to a single port on the same network device. Ingress SPAN allows the monitoring of some or all packets that ingress a specified port or ports. Egress SPAN allows the monitoring of some or all packets that egress a specified port or ports. RSPAN allows the delivery of the replicated traffic to a port on a remote network device. Filtering may be applied, for example, to SPAN packets having selected virtual storage area network numbers.
