FLUID DIFFUSION LAYERS WITH IN-PLANE PERMEABILITY CHARACTERISTICS FOR IMPROVED PERFORMANCE IN FUEL CELLS

摘要

Water management in solid polymer electrolyte fuel cells may be affected by the in-plane permeability characteristics of component fluid diffusion layers. In solid polymer electrolyte fuel cell stacks, performance can be improved by employing fluid diffusion layers in the stack that all have acceptably low in-plane permeability.
