The invention discloses a method for manufacturing a foamed nickel, molybdenum and cobalt ternary alloy material. Urethane foam is used as a die plate which is subject to surface conductance through chemical nickel plating or conductive colloid coating; the nickel, molybdenum and cobalt ternary alloy is electrodeposited; finally the die plate of the urethane foam is removed in a pyrolyzing furnace and reduction treatment is carried out in a hydrogen atmosphere furnace to manufacture the foamed nickel, molybdenum and cobalt ternary alloy material. The material manufactured by the invention is of three-dimensional network structure and has high open-cell rate, big specific surface area and good corrosion resistance, thus is a high-performance electrode material in hydrogen evolution process.
