Effect of Gas Channel on Water Formation in Polymer Electrolyte Fuel Cell : 2nd Report, Experimental and Three-Dimensional Analyses with Lattice Gas Automaton Method

摘要

Water management is the most important subject in the development of the Polymer Electrolyte Fuel Cells (PEFC) with high performance and high reliability. Experimental and three-dimensional numerical study has been done for the serpentine channel. Two kinds of the channel width, 2mm and 8mm, were selected. It is found that the rib of each separator plays as the coverage to reduce the escaping of the water content from the GDL to the channel.
