  • Corrosion resistant gas diffusion layer with a micro protective layer for electrochemical cells
    Patent number: 7909969
    Abstract: A gas diffusion layer with a micro protective layer is utilized in the electrochemical cells. The cell mainly includes end plates, current collectors, flow field plates, gas diffusion layers, catalyst layers, a proton exchange membrane and a circuit unit. When the cell functions as a fuel cell, hydrogen reacts with oxygen to generate electricity and water. Reversely, when the cell functions as a water electrolysis cell, water was decomposed electrolytically to produce hydrogen and oxygen gases. In this manner, the present invention particularly has the gas diffusion layer to be coated with a micro protective layer so as to prevent the gas diffusion layer from being corroded by active oxygen species generated within the oxygen electrode under the catalysis during water electrolysis operation.
