Humidity regulation control system and method for fuel cell

The invention discloses a fuel cell humidity regulation control system and method. The fuel cell humidity regulation control system comprises an electric pile, an intercooler, a humidifier, a humidity sensor and a controller, the intercooler is used for cooling the introduced air to obtain cooled air and introducing the cooled air into the humidifier; the humidifier is used for humidifying the introduced cooling air to obtain humidified air and introducing the humidified air into an electric pile of the battery; the humidity sensor is used for acquiring the humidity of the humidified air; and the controller is used for adjusting the temperature of the cooling air when the humidity of the humidified air is not within the humidity demand range of the electric pile, so that the humidity of the humidified air is within the humidity demand range of the electric pile. According to the technical scheme, the humidity of the humidified air can be adjusted by adjusting the temperature of the cooling air introduced into
