Abstract: A catalyst, a preparation method therefor, an electrode containing the catalyst, a membrane-electrode assembly, and a fuel cell are disclosed. The catalyst contains a support; metal particles supported by the support; and a coating layer located on the metal particles, and includes any one selected from the group consisting of phthalocyanine, M-phthalocyanine (wherein M is a transition metal) and a mixture thereof. The catalyst has improved durability since a coating layer is formed on the surface of a commercial catalyst or a conventional catalyst through a relatively easy method without separate treatment. A carbon coating layer formed by post-treating a catalyst including the coating layer further improves durability. Material transfer ability and performance are also improved by a carbon nanofiber or a carbon nanotube generated during post-treatment.
