  "textContent": "To provide a technique that achieves improvement of the performance of outputting water from a catalyst layer in a membrane electrode assembly. [0002] A membrane electrode assembly includes an electrolyte membrane and a cathode catalyst layer 31 formed on one surface of the electrolyte membrane. The cathode catalyst layer 31 includes catalyst supporting carbon 51 and an ionomer 52. The catalyst supporting carbon 51 includes a carbon particle 511 and a catalyst particle 512 supported on the carbon particle 511. The cathode catalyst layer 31 includes a water-repellent carbon particle 53 with a fluorine group. As a result, the performance of outputting water from the cathode catalyst layer 31 is improved.",
