  • Proton conductive hybrid material, and catalyst layer for fuel cell using the same
    Patent number: 8632701
    Abstract: This invention provides an organic-inorganic hybrid material, which can exhibit high proton conductivity in a wide temperature range of a low temperature to a high temperature, a proton conductive material, which has a small particle diameter, that is, has a particle diameter capable of reaching pores of primary particles of carbon powder or the like, and has controlled particle diameters, a catalyst layer containing these materials for a fuel cell and an electrolyte film containing these materials for a fuel cell, and a fuel cell. The proton conductive hybrid material comprises proton conductive inorganic nanoparticles and a proton conductive polymer, wherein the Stokes particle diameter of the proton conductive hybrid material by dynamic light scattering is not more than 20 nm.
