The invention discloses a membrane electrode, a fuel cell and a preparation method and application thereof. The membrane electrode includes an anode catalytic layer, a cathode catalytic layer and a proton exchange membrane; the anode catalytic layer includes the following components: Pt/C, hydrophilic carbon nanotubes and resin; the cathode catalytic layer includes the following components: Pt/C, hydrophilic carbon nanotubes and resin; in the cathode catalytic layer, the mass fraction of the hydrophilic carbon nanotubes in the total mass of the cathode catalytic layer is 13%-19%. When the membrane electrode of the present invention is applied to a fuel cell, it has good water retention and good proton conductivity, so that the discharge performance and discharge efficiency are better, and the battery performance is greatly improved. |
