Disclosed herein are a method of manufacturing a fuel cell, and a fuel cell manufactured according to the method. The method includes bonding a sub-gasket, provided with an air inlet and a hydrogen inlet, to a side surface of a three-layer membrane-electrode assembly (MEA) including an electrolyte membrane, a cathode located on one surface of the electrolyte membrane, and an anode located on the other surface of the electrolyte membrane; stacking a gas diffusion layer, which comprises an antioxidant precursor, on at least one of the cathode and the anode and preparing a five-layer MEA; and applying a current to the five-layer MEA and moving an antioxidant, which is derived from the antioxidant precursor, to the electrolyte membrane.

Provided is a method of manufacturing a supported catalyst and a supported catalyst manufactured using the same. The method may prevent the growth of catalytic metal particles by repeatedly applying heat, so the method is simpler and more economical than conventional processes. Moreover, since the support in the supported catalyst thus manufactured includes a hollow having a predetermined size, an electrode manufactured using the supported catalyst may ensure a desired electrode thickness even when used in a relatively small amount compared to the conventional technology. Moreover, water generated during operation of a fuel cell can be efficiently discharged, so desired mass transfer resistance can be exhibited, and a high electrochemically active surface area (ECSA) and superior catalytic activity can be attained.

A heat treatment method performed to form a particle structure of a carbon-supported metal catalyst includes preparing the carbon-supported metal catalyst by supporting metals on a support including carbon. The heat treatment method also includes applying heat shock to the carbon-supported metal catalyst. The applying heat shock to the carbon-supported metal catalyst includes raising a temperature of the carbon-supported metal catalyst to a first temperature and lowering the temperature of the carbon-supported metal catalyst to a second temperature. A difference between the first temperature and the second temperature is 500&#xb0; C. to 1,100&#xb0; C. The applying heat shock to the carbon-supported metal catalyst is repeated at least once. A carbon-supported metal catalyst is prepared by the heat treatment method.
