Abstract
Disclosed is an organic/inorganic composite electrolyte membrane comprising: (a) a sulfonated fluorine-free hydrocarbon-based polymer; and (b) inorganic particles capable of collecting moisture, wherein the inorganic particles include zeolite. Also, disclosed are an electrode comprising the zeolite as a component for forming a catalyst layer, a membrane electrode assembly comprising the electrolyte membrane and/or the electrode, and a fuel cell having the membrane electrode assembly. The organic/inorganic composite electrolyte membrane using the hydrophilic zeolite in combination with the sulfonated fluorine-free hydrocarbon-based polymer shows high proton conductivity, and thus can impart excellent quality to a fuel cell even under high-temperature and low-humidity conditions.
