  • Patent number: 11289711
    Abstract: Disclosed are a catalyst electrode for a fuel cell, a method for fabricating the catalyst electrode, and a fuel cell including the catalyst electrode. The presence of an ionomer-ionomer support composite in the catalyst electrode prevents the porous structure of the catalyst electrode from collapsing due to oxidation of a carbon support to avoid an increase in resistance to gas diffusion and can stably secure proton channels. The presence of carbon materials with high conductivity is effective in preventing the electrical conductivity of the electrode from deterioration resulting from the use of a metal oxide in the ionomer-ionomer support composite and is also effective in suppressing collapse of the porous structure of the electrode to prevent an increase in resistance to gas diffusion in the electrode. Based on these effects, the fuel cell exhibits excellent performance characteristics and prevents its performance from deteriorating during continuous operation.

    Abstract: A sealing part has an outer peripheral point of the sealing part within a range from 0 degree to 90 degrees around a center point of the sealing part relative to a stacking direction, and that is located at a distance of a first length L1 from the center point. Each point on the outer peripheral line within a first range satisfies L2?L1, where L2 is a second length that is a distance from the center point to that point. Each point on the outer peripheral line within a second range satisfies L3<L1, where L3 is a distance from the center point to that point, and is located on the opposite side of the outer peripheral point from the center point or at the same position as the outer peripheral point in the direction perpendicular to the stacking direction.

  • Patent number: 10930406
    Abstract: Disclosed is a liquid-phase oxidative decomposition method for radioactively contaminated carbonaceous material, providing a method of oxidizing carbon into a gas in liquid phase to treat radioactively contaminated carbonaceous material. The method comprises the following steps: ball milling a mixture of a molybdenum-containing substance and a carbonaceous material, thermally treating the ball milled mixture, and performing liquid-phase oxidation of the thermally treated mixture. The thermal treatment causes carbon to enter space between molybdenum atoms so as to reduce the particle size of carbon and improve the chemical reactivity of carbon, and an oxidant is then used to oxidize the carbon in the space between molybdenum atoms into a gas in liquid phase, while the molybdenum-containing moiety is converted into a water-soluble substance.

  • Patent number: 10886549
    Abstract: Simplified methods are disclosed for preparing a catalyst coated membrane that is reinforced with a porous polymer sheet (e.g. an expanded polymer sheet) for use in solid polymer electrolyte fuel cells. The methods involve forming a solid polymer electrolyte membrane by coating membrane ionomer solution onto a first catalyst layer and then applying the porous polymer sheet to the membrane ionomer solution coating, while it is still wet, such that the membrane ionomer solution only partially fills the pores of the porous polymer sheet. A second catalyst ink is then applied which fills the remaining pores of the porous polymer sheet. Not only are such methods simpler than many conventional methods, but surprisingly this can result in a marked improvement in fuel cell performance characteristics.

  • Patent number: 10840526
    Abstract: A method of evaluating a movement tendency of ions in an electrolyte membrane includes counting inter-movement ions, counting intra-movement ions and calculating the ratio of the intra-movement ions and inter-movement of ions. The movement tendency of ions is predicted based on the ratio. In the case of evaluating a movement tendency of ions using the method, since the structure of the electrolyte membrane in which the ratios of intra-movement and inter-movement are maximized is predicted through measurement of the ratios of the intra-movement and inter-movement of ions, ohmic resistance that may occur in a membrane-electrode assembly (MEA) may be reduced. The electrolyte membrane having the optimal structure predicted by the method can be applied to a fuel cell to increase its performance.
