1. A method of preparing a fuel cell element, said method comprising:

  • providing a plurality of fibers and/or a porous electrode material;

    depositing a nanoparticle catalyst on said plurality of fibers and/or porous electrode material;

    forming nanoparticles on said plurality of fibers and/or porous electrode material using said nanoparticles catalyst;

    forming a catalytically active layer comprising a substantially continuous thin film on said nanoparticles thereby forming a fuel cell element comprising a plurality of fibers bearing nanoparticles partially or fully coated with a catalytically active thin film;

    wherein said thin film comprises an alloy having the formula;


    PtxVyCozNiw wherein;

    x is greater than 0.06 and less than 1;

    y, z, and w are independently greater than zero and less than 1; and

    x+y+z+w=1.
