A fuel composition for a fuel cell includes at least one primary fuel that produces protons and electrons, and at least one peroxide. As an example, the primary fuel may be at least one aqueous solution containing methanol, ethanol, or formic acid. When the fuel composition is used, the catalytic activity can increase, and thus a fuel cell having improved performance can be manufactured.
