The invention provides a fule cell of planer aligned type, being capable of restrain short circuit between adjacent single-cells. The fuel cell 10 includes a membrane electrode assembly 20. The membrane electrode assembly 20 has an electrolyte membrane 22, cathode catalyst layers 24a-d, and anode catalyst layers 26a-d disposed counter to the cathode catalyst layers 24a-d with the electrolyte membrane 22 disposed between the cathode catalyst layers 24a-d and the anode catalyst layers 26a-d. Cathode-side insulating layers 40, which are water-repellent, are arranged between the adjacent cathode catalyst layers 24. The surface of the cathode-side insulating layer 40 on the opposite side of the electrolyte membrane 22 is protruded relative to the surface of the adjacent cathode catalyst layers 24. Anode-side insulating layers 42a-c, which are water-repellent, are arranged between the adjacent anode catalyst layers 26. The surface of the anode-side insulating layer 42 on the opposite side of the electrolyte membran
