An at least ternary metal alloy of the formula, AB(5-Y)X(y), is claimed. In this formula, A is selected from the rare earth elements, B is selected from the elements of groups 8, 9, and 10 of the periodic table of the elements, and X includes at least one of the following: antimony, arsenic, and bis
An at least ternary metal alloy of the formula, AB(5-Y)X(y), is claimed. In this formula, A is selected from the rare earth elements, B is selected from the elements of groups 8, 9, and 10 of the periodic table of the elements, and X includes at least one of the following: antimony, arsenic, and bismuth. Ternary or higher-order substitutions, to the base AB5 alloys, that form strong kinetic interactions with the predominant metals in the base metal hydride are used to form metal alloys with high structural integrity after multiple cycles of hydrogen sorption.

A fuel cell, comprising: an electrolyte; an anode in contact with the electrolyte, the anode being made of a material selected to electrocatalyze a fuel; a cathode contacting the electrolyte, the cathode being made of a material selected to electrocatalyze oxygen, the cathode material being an alloy
A fuel cell, comprising: an electrolyte; an anode in contact with the electrolyte, the anode being made of a material selected to electrocatalyze a fuel; a cathode contacting the electrolyte, the cathode being made of a material selected to electrocatalyze oxygen, the cathode material being an alloy having the formula: AB5-YXY as an atomic ratio; wherein A includes at least one element selected from the group consisting of the rare earth metals; B includes at least one element selected from the group consisting of iron, ruthenium, osmium, cobalt, rhodium, iridium, nickel, palladium, platinum, copper, silver, gold, zinc, manganese, cadmium, mercury, and aluminum; X includes at least one element, E, selected so that at least one binary alloy selected from the group consisting of AE and BX BE has an enthalpy of formation greater than that of the enthalpy of formation of the binary alloy LaSn; and Y is greater than or equal to zero.
