Disclosed is a method of preparing a catalyst having a conductive oxide protective layer. The method may include providing (e.g., supplying) a carbon support having a metal catalyst supported thereon to a fluidized bed reactor, and forming a conductive oxide protective layer using atomic layer deposition (ALD). Particularly, the atomic layer deposition may include supplying a conductive oxide precursor to the fluidized bed reactor, conducting a first purging by supplying an inert gas to the fluidized bed reactor, converting the conductive oxide precursor to conductive oxide by supplying a reactive gas to the fluidized bed reactor, and conducting a second purging by supplying an inert gas to the fluidized bed reactor.
