Abstract: A membrane-electrode assembly for a fuel cell including a first substrate and a second substrate and a catalyst layer between the first substrate and the second substrate is provided, where the first substrate is a polymer electrolyte membrane and the second substrate is a electrode substrate, or the first substrate is the electrode substrate and the second substrate is the polymer electrolyte membrane. The catalyst layer has a h1/t1 ratio of about 0.5 or more, where s1 represents a point on the first substrate at one end of the catalyst layer, h1 represents a distance between the first substrate and the second substrate, s2 represents a point on the first substrate closest to s1 at which a height (h) of the catalyst layer becomes h1, and t1 represents the distance between the s1 and the s2. The membrane-electrode assembly can include a greater amount of catalyst by decreasing a shadow effect, and thereby increasing its energy density.
