Fuel cell arrangement for use in fuel cell system for creating driving power in vehicle, has plate module including pair of flow structures for guiding oxidant with channels that are coupled together through water or water vapor diffusion

摘要

The arrangement (1) has a cathode plate module including a pair of flow structures (13) for guiding oxidant with two channels (11a, 11b), where the channels are arranged adjacent to each other in the flow structures, so that heat transfer is made between the channels and directions of the flow of the channels are aligned in normal operation of the arrangement. A region (I) is arranged adjacent to another region (II) and the channels are coupled together through water or water vapor diffusion.
