Abstract: The present disclosure relates to a styrene-based copolymer for an electrode binder of a solid alkaline fuel cell, represented by the following Chemical Formula 1, an electrode binder including the same, and a membrane electrode assembly including the electrode binder. The electrode binder for a solid alkaline fuel cell is obtained by dispersing the styrene-based copolymer for an electrode binder in a mixed solvent of alcohol with water. Thus, even when coating electrode catalyst slurry including the electrode binder directly on an electrolyte membrane, the electrolyte membrane is not damaged so that the quality of a solid alkaline fuel cell using the same may be improved. wherein x is an integer of 2-10, and each of m and n represents the number of repeating units.
