ABSTRACT:
Provided are an additive to an electrode for a fuel cell that is a proton conductive compound having at least one phosphate group, an electrode for a fuel cell including the same, a method of manufacturing the electrode for a fuel cell, and a fuel cell using the electrode. The additive to an electrode for a fuel cell improves the durability of a fuel cell and reduces the amount of phosphoric acid discharged during operation of the fuel cell by fixing the phosphoric acid. Accordingly, a fuel cell having improved efficiency may be prepared using the additive because of improved proton conductivity and durability.
