According to one embodiment, fuel cell includes an anode, into which an aqueous methanol solution is introduced as fuel, includes a current collector and a catalyst layer formed on the current collector, a cathode, into which an oxidizing agent is introduced, includes a current collector and a catalyst layer formed on the current collector, and an electrolyte membrane interposed between the catalyst layer of the anode and the catalyst layer of the cathode. The catalyst layer of at least one of the anode and the cathode contains carbon particles having pores on the surface thereof, catalyst microparticles which are supported by these carbon particles and are finer than the carbon particles, a perfluoroalkylsulfonic acid polymer and a high-molecular compound having a repeating unit of a high-molecular chain fixed to the surface of the carbon particles.
