ABSTRACT:
A powdery raw material for manufacturing an anode of a fuel cell comprises a powder of a nickel-base alloy consisting essentially of 0.5-10 percent by weight aluminum, and the balance of nickel and inevitable impurities, and having a mean grain size of 3-20 microns. The nickel-base alloy powder may contain 0.01-1.0 percent by weight oxygen, and/or may have an apparent density of 0.5-3.5 g/cm.sup.3, and a specific surface area of at least 0.12 m.sup.2 /g. Advantageously, the nickel-base alloy powder is formed by means of water-atomization under a condition that the water injection pressure is 400 Kg/cm.sup.2, and the specific water quantity is 0.02-0.2 m.sup.3 /Kg, the thus manufactured anodes exhibit initial anode characteristics as excellent as those of conventional anodes, and possess such excellent high-temperature creep strength and sintering resistance, thereby exhibiting excellent anode characteristics over a long period of time.
