    • Proposed is a PEM fuel cell that comprises a separator plate assembly with a charging chamber, which is partitioned off by a partition wall and via charging spots has a fluid connection to an adjoining cathode chamber. The partition wall is designed so that the depths of the charging channels in the charging chamber and the depths of the distribution channels in the adjoining cathode chambers change in such a way that the quantity of oxidant that is charged at a charging spot from the charging chamber into the cathode chamber can be fixed in advance. As a result, the charging of oxidant, which has not been humidified or only slightly, into the cathode chamber can be improved with regard to the curve of the relative humidity along the cathode. Also proposed is a method for manufacturing a separator plate assembly suitable for a PEM fuel cell.
    • 提出了一种PEM燃料电池,其包括具有充电室的隔板组件,其由分隔壁分隔开,并且经由充电点具有与相邻阴极室的流体连接。 分隔壁被设计成使得充电室中的充电通道的深度和相邻的阴极室中的分配通道的深度以这样的方式变化,使得从充电室在充电点处被充电的氧化剂的量 进入阴极室可以预先固定。 结果,可以相对于沿着阴极的相对湿度的曲线,改善尚未加湿或仅稍微加入到阴极室中的氧化剂的充电。 还提出了一种制造适用于PEM燃料电池的隔板组件的方法。
