The present invention includes a catalyst for a fuel cell which contains a transition element core, and a surface layer that contains at least one selected from the group including platinum, a platinum-transition element alloy, and a combination thereof, and that exists on the surface of the core. The catalyst being prepared without a surfactant.

Catalyst for fuel cell, method for preparing the same, and membrane-electrode assembly and fuel cell system comprising same

An ion-conductive composite membrane and a method of manufacturing the same, the membrane including phosphate platelets, a silicon compound, and a Keggin-type oxometalate and/or Keggin-type heteropoly acid, wherein the phosphate platelets are three-dimensionally connected to each other via the silicon compound. An electrolyte membrane having an ion-conductive inorganic membrane or an ion-conductive organic/inorganic composite membrane effectively prevents crossover of liquid fuel without the reduction of ion conductivity in a liquid fuel cell, thereby allowing for the production of fuel cells having excellent performance.
