Abstract
Disclosed are an electrode for a fuel cell a membrane-electrode assembly including the same, and a method of preparing the same. The electrode may include catalyst particles; and a binder in which the catalyst particles are dispersed. In particular, the binder may include an ionomer having proton conductivity and a polymer of intrinsic microporosity (PIM) in order to implement high oxygen permeability.
