    • The invention relates to flow module for a fuel cell comprising and polymer electrolyte membrane (PEM), said module supporting compensation of partial water vapor pressure using simple means thereby countering the drying of areas in the membrane even when the process gases fed to the fuel cell are only slightly humid or not humid at all. The flow module comprises at least one inlet (1) and at least one outlet (2) for a gas that is to be guided by means of an electrode of the fuel cell. The surface of the flow module that faces the electrode is structured in such a way that al least one channel (3) connecting the inlet (1) and the outlet (2) is formed between the flow module and the electrode. According to the invention, the at least one inlet (1) and the at least one outlet (2) are arranged and the at least one channel (3) is guided in such a way that the segments of the channel having a higher relative humidity are arranged in the vicinity of the segments of the channel having a lower relative humidity so that the humidity gradient on the PEM is balanced out.
    • 本发明涉及一种包括聚合物电解质膜(PEM)的燃料电池的流量模块,所述模块使用简单的装置支持部分水蒸汽压力的补偿,从而即使当进料到燃料电池的工艺气体时也抵抗膜中的区域的干燥 根本没有潮湿或潮湿。 流动模块包括用于通过燃料电池的电极引导的气体的至少一个入口(1)和至少一个出口(2)。 流动模块面对电极的表面被构造成使得在流动模块和电极之间形成连接入口(1)和出口(2)的至少一个通道(3)。 根据本发明,布置至少一个入口(1)和至少一个出口(2),并且使得至少一个通道(3)以使得通道的段具有较高相对湿度 布置在具有较低相对湿度的通道的段附近,使得PEM上的湿度梯度平衡。
