Fuel cell anodes comprising (a) a catalyst comprising Pt, (b) an oxygen evolution reaction catalyst, and (c) at least one of Au, a refractory metal (e.g., at least one of Hf, Nb, Os, Re, Rh, Ta, Ti, W, or Zr), a refractory metal oxide, a refractory metal boride, a refractory metal carbide, a refractory metal nitride, or a refractory metal silicide. The fuel cell anodes are useful in fuel cells. 1. A hydrogen fuel cell anode comprising:a catalyst comprising Pt, the catalyst having surface area;an oxygen evolution reaction catalyst on a portion of the surface area of the catalyst comprising Pt; andat least one of Au, a refractory metal, a refractory metal boride, a refractory metal carbide, a refractory metal nitride, or a refractory metal silicide on a portion of the surface area of the catalyst comprising Pt, wherein the refractory is one of a refractory metal, a refractory metal boride, a refractory metal carbide, a refractory metal nitride, or a refractory metal silicide is independently selected from the group consisting of Hf, Nb, Os, Re, Rh, Ta, Ti, W, Zr, and combinations thereof,wherein a portion of the surface area of the catalyst comprising Pt is not covered by either the oxygen evolution reaction catalyst or collectively the Au, the refractory metal, refractory metal boride, refractory metal carbide, refractory metal nitride, and refractory metal silicide to the extent present.2. (canceled)3. The hydrogen fuel cell anode of claim 1 , wherein Pt present in the catalyst comprising Pt is present as at least one of metallic Pt or Pt compound claim 1 , and wherein the catalyst comprising Pt further comprises at least one of Ir claim 1 , Ru claim 1 , or Pd.4. The hydrogen fuel cell of claim 1 , wherein at least some of the least one of Ir claim 1 , Ru claim 1 , or Pd is present in at least one organometallic compound claim 1 , and wherein at least some of the least one of Ir claim 1 , Ru claim 1 , or Pd is present in at least one organometallic complex.5.
