    Abstract: A fuel cell separator, a fuel cell stack having the fuel cell separator, and a reactant gas control method of the fuel cell stack are provided. That is, even when the fuel cell stack operates under the low load operation condition, a reactant gas is supplied to the reactant gas passages of the fuel cell separator, and thus, the length of the passage can be shortened by 50% as compared with the prior art having only one reactant gas passage. Therefore, the reactant gas can be effectively supplied without experiencing pressure loss. Further, in the high load operation of the fuel cell stack, the reactant gas is introduced into the first reactant gas passage of the fuel cell separator and utilized in half of the whole electrode area. Subsequently, the reactant gas is introduced into the second reactant gas passage and utilized in the remaining half of the electrode area. The flow rate of the reactant gas flowing along the passage channels is increased by two times, even when the reactant gas utilizing rate is identical as compared with the reactant gas flow in the low load operation. As a result, the moisture existing in the passage channels can be more effectively discharged and the flooding phenomenon occurring in the high load operation can be prevented. By controlling the reactant gas supply in accordance with an operation condition of the fuel cell stack without experiencing pressure loss and deterioration of the utilizing rate, the flooding phenomenon and concentration polarization phenomenon that occur in the fuel cell stack can be prevented.

    Abstract translation: 提供燃料电池隔板，具有燃料电池隔板的燃料电池堆和燃料电池堆的反应气体控制方法。 也就是说，即使燃料电池堆在低负载运转条件下运转，向燃料电池用隔板的反应气体通路供给反应气体，因此与通常的通路长度相比可以缩短50％ 现有技术仅具有一个反应气体通道。 因此，能够有效地供给反应气体而不会发生压力损失。 此外，在燃料电池堆的高负荷运转中，将反应气体导入燃料电池用隔板的第一反应气体通路，并用于整个电极区域的一半。 随后，反应气体被引入到第二反应气体通道中，并用于电极区域的剩余部分。 即使反应物气体的利用率与低负荷运转中的反应气体流量相同，流过通道的反应气体的流量增加了两倍。 结果，可以更有效地排出存在于通道通道中的水分，并且可以防止在高负载操作中发生的溢流现象。 通过根据燃料电池堆的操作条件控制反应气体的供给而不会发生压力损失和利用率的劣化，可以防止在燃料电池堆中发生的溢流现象和浓缩极化现象。

    Abstract: A memory system is provided includes a host processor, and a plurality of cascade connected memory cards connected to the host processor. Each of the memory cards stores a same default relative card address (RCA) prior to initialization of the memory system. The host processor is configured to sequentially access each memory card using the default RCA, and to change the default RCA to a unique RCA upon each sequential access.

    Abstract: A semiconductor memory device performing an erase operation using an erase gate and a method of manufacturing the same are provided. The memory device may include a charge trap layer storing a first charge transfer medium having a first polarity and at least one erase gate. The at least one erase gate may be formed below the charge trap layer. A second charge transfer medium, which has a second polarity opposite to the first polarity, may be stored in the at least one erase gate. During the erase operation, the second charge transfer medium migrates to the charge trap layer causing the first charge transfer medium to combine with the second charge transfer medium.

    Abstract: A method and system for providing a data service in interworking wireless public and private networks, allows for data service data being transmitted through the private network when a data service is to be transmitted through the private network within the network where the wireless public network and the wired/wireless private network are interworked. A method of providing a data service in interworking wireless public and private networks, includes transmitting, by a user, a data service request signal; determining, by the private network, based on identifier information through which of the private and public networks to transmit the data service; transmitting a private network data service call to a private content server when it is determined based on the identifier information that it is the private network data service call; and transmitting a public network data service call to a public network content server when it is determined based on the identifier information that it is the public network data service call. Consequently, there is an advantage that a packet data service can be forwarded through any one selected from the public network and the private network. Further, there is another advantage that a data service is available through the private network by modifying the system without changing each user terminal, and thus an additional cost is hardly caused.
