Provided is an electrocatalyst for anion exchange membrane water electrolysis, including a carbonaceous material, and nickel electrodeposited on the carbonaceous material, wherein nickel is partially substituted with platinum and the substitution with platinum provides increased hydrogen evolution activity as compared to the same electrocatalyst before substitution with platinum. Also provided are a method for preparing the electrocatalyst and an anion exchange membrane water electrolyzer using the same. The nickel electrocatalyst coated with an ultralow loading amount of platinum for anion exchange membrane water electrolysis shows excellent hydrogen evolution activity and has a small thickness of catalyst, thereby providing high mass transfer and high catalyst availability. In addition, the electrocatalyst uses a particle-type electrode to facilitate emission of hydrogen bubbles generated during hydrogen evolution reaction and oxygen bubbles generated during oxygen evolution reaction, and requires low cost for preparation to provide high cost-efficiency.

Disclosed are a platinum (Pt)-free, palladium (Pd)-yttrium (Y) alloy catalyst having superior oxygen reduction reaction activity and stability, a method for preparing the same, and a fuel cell including the catalyst. Since the Pt-free Pd&#x2014;Y catalyst is inexpensive, it may be usefully applicable for fuel cells, particularly polymer electrolyte membrane fuel cells.

Disclosed is a method for fabricating a carbon material, by which carbon fibers or carbon tubes, particularly branched carbon fibers or carbon tubes, are obtained via a so-called self-growing process without using external carbon sources. The carbon material obtained by the method has a large specific surface area and further includes a metal catalyst, and thus may be used in cell materials for a fuel cell or secondary battery, hydrogen storage devices, capacitors, solar cells, display panel or the like.
