Fuel cell

Abstract

A fuel cell includes a membrane electrode assembly. The membrane electrode assembly has an electrolyte membrane, cathode catalyst layers, and anode catalyst layers disposed counter to the cathode catalyst layers with the electrolyte membrane disposed between the cathode catalyst layers and the anode catalyst layers. Cathode-side insulating layers, which are water-repellent, are provided between the adjacent cathode catalyst layers. The surface of the cathode-side insulating layer on the opposite side of the electrolyte membrane is protruded relative to the surface of the adjacent cathode catalyst layers. Anode-side insulating layers, which are water-repellent, are provided between the adjacent anode catalyst layers. The surface of the anode-side insulating layer on the opposite side of the electrolyte membrane is protruded relative to the surface of the adjacent anode catalyst layers.
