The invention relates to the technical field of fuel cells, in particular to a fuel cell gas supply system and a control method, and the fuel cell gas supply system comprises an air compressor, a first throttle valve and a gas storage tank; the first throttle valve is connected between the electric pile assembly and the air compressor; the air storage tank is connected to the air inlet end and the air outlet end of the first throttle valve in parallel, and the air inlet end and the air outlet end of the air storage tank are provided with a second throttle valve and a third throttle valve respectively. The air storage tank is introduced into the fuel cell air supply system, so that the working point of the air compressor and the air supply demand of the fuel cell system can be decoupled, the working point of the air compressor can be adjusted in real time to be always close to an efficient area, the rotating speed change of the air compressor is smoother, and the air compressor and the air storage tank can sup
