Abstract
The present invention provides a method for manufacturing a catalyst for a fuel cell which may not be poisoned by an ionomer. Specifically, the method includes: loading a catalyst on a support, coating a carbon layer having a predetermined thickness on the surface of the support, and exposing the catalyst to the outside by removing at least a part of the carbon layer.
