Fuel cell system and fuel cell

The invention discloses a fuel cell system and a fuel cell. The fuel cell system comprises: a first air compressor; the air inlet pipe is connected with the air inlet end of the first air compressor; the water spraying mechanism comprises a water sprayer, and the water sprayer is installed on the air inlet pipe. According to the fuel cell system disclosed by the invention, the liquid water is sprayed into the air inlet pipe of the air compressor for providing the compressed air for the cathode of the electric pile, so that the temperature of the compressed air can be reduced, the power consumption of the air compressor is reduced, and meanwhile, the compressed air can be humidified. Besides, liquid water is sprayed out and atomized by the water sprayer and then mixed with air to enter the air compressor, and the liquid water in the mixed gas is gasified to absorb a large amount of heat generated by the compressed air by utilizing the characteristic of high latent heat of gasification of the water, so that the
