Abstract: A method and system for connection management in a wireless data network, such as a 1xEV-DO network adds connections to new network sectors upon receipt of a connection request from an active terminal, but removes data connections that the active terminal requests to be dropped only after confirmation from the active terminal that a channel allocation message has been received and applied. The active network maintains an active set of connections that is at least as large as the active set maintained by the active terminal and does not initiate a connection termination if no confirmation of the channel allocation message is received. This allows for a reduction in the number of dropped connections.

Abstract: Disclosed is a flow-field plate and fuel cell stack using the same. The flow-field plate of the present invention comprises a center hole (5) formed at the center of the flow-field plate, a inlet (6) and a outlet (7) formed on two positions near the outer edge of the flow-field plate, and flow grooves extending radially from the center hole (5) on one side of the flow-field plate. Since the flow-field plate according to the present invention may comprise flow grooves extending radially and having short flow path, which is benefit for reactants diffusion, there is no “dead-end” on the flow-field plate and reactants may distribute uniformly to each part of flow-field plate. Furthermore, resultants generated from reaction, such as water, nitrogen, carbon dioxide, etc., may be discharged in time and not accumulate on flow-field plate. Therefore, the reactant utilization ratio, the fuel cell performances and its service life may be improved.
