Measurement of Produced Water Behavior in PEFC Short Stack by Using a Self-water Management Type of a Metallic Separator

聚合物电解质燃料电池（PEFC）的水管理是实现电池性能提升和长期稳定运行的重要问题。本研究的目的是开发一种具有自我水管理功能的金属分离器。对MIM法制备的金属分离器组成的PEFC短堆制备金属多孔介质的基本性能进行了评价。此外，建立了PEFC堆的可视化技术，以确定MIM分离器的水管理情况。

Water management of a polymer electrolyte fuel cell (PEFC) is an important issue in the realization of cell performance improvement and long-term stable operation. The objective of this study is the development of a metallic separator with a self-water management function. The PEFC short stack composed of the metallic separator made by MIM method that could make metallic porous medium was evaluated about the basic property. Moreover, the visualization technique for a PEFC stack was established for confirmation of the water management of the MIM separator.
