The invention provides an air-side inlet air temperature and humidity combined control device of a fuel cell, belongs to the technical field of fuel cells, and solves the problems that in the prior art, the temperature control response of an intercooler is too slow, and the humidity cannot be accurately regulated and controlled. The device comprises an expansion machine, a humidifying cavity, a tail exhaust throttle valve, a water pump, a thermostat, a water distribution piece, a first water storage tank and a second water storage tank. Wherein the first water storage tank is a constant-temperature water storage tank with a built-in electric heating mechanism, and the second water storage tank is a cold water tank adopting an external water injection mode. An air inlet of the electric pile is connected with a pressing wheel cavity of the expansion machine through a humidifying cavity, and an air tail gas outlet is connected with a water injection opening of the first water storage tank sequentially through a
