  • Oxidant flow field for solid polymer electrolyte fuel cell
    Patent number: 6663997
    Abstract: In solid polymer electrolyte fuel cells, a laminar flow of a dilute oxidant stream, for example air, may be disrupted by incorporating obstacles in the channels of an oxidant flow field. The laminar flow is changed to turbulent flow thereby enhancing the flow of oxygen to the membrane electrode assembly in the fuel cell and improving fuel cell performance.
    Type: Grant
    Filed: December 22, 2000
    Date of Patent: December 16, 2003
    Assignee: Ballard Power Systems Inc.
    Inventors: Zuomin Dong, Ken W. Kratschmar, Dongming Lu, Ryan N. Mackie, Walter R. Merida Donis, Michael E. Pastula, Martin L. Perry, Gaofeng Gary Wang, Rong Zheng
