  "textContent": "A method for preparing a cathode catalyst layer structure for a membrane electrode assembly of a fuel cell includes forming a cathode catalyst layer structure having at least a first catalyst layer and a second catalyst layer. The second catalyst layer is configured to be positioned closer to a proton exchange membrane of the membrane electrode assembly than the first catalyst layer, the first catalyst layer is formed from a first slurry, and the second catalyst layer is formed from a second slurry. An average particle diameter of a platinum catalyst, a specific surface area of a carbon support, an I/C ratio, and a weight percentage of the platinum catalyst are selected based on the total weight of the carbon support and the platinum catalyst in each of the first slurry and the second slurry.",
