An electrical contact carrier strip includes a main body, a plurality of electrical contacts integrally formed with and connected to the main body, and a plurality of support tabs extending from the main body. The cluster nodes accept the request information to transfer the same to the next transfer destinations according to the node list or to the master node if the next transfer destinations do not exist. The vapor relief valve allows vapor to gradually be delivered from the vapor separator to an air induction system depending on the amount of air entering the air induction system andor engine speed. The interior and exterior surfaces each define respective surface planes. On a periphery of one side of a polymer electrolyte fuel-cell separator, the composition forms a seal member which allows for little leaching of non-functional organopolysiloxane fraction and has improved acid resistance and compression set. The buffered message queue architecture provides better performance and scalability since no persistent operations are needed and no UNDOREDO logs need to be maintained.
