ABSTRACT:
There are provided a pump of a noise suppression and vibration proof structure and a fuel cell system using the same. The fuel cell system includes at least one electricity generator including an electrolyte membrane and an anode and a cathode attached to the both surfaces of the electrolyte membrane to generate electricity energy by the electrochemical reaction between fuel containing hydrogen and oxidant supplied to the anode and the cathode, a fuel supplying unit including a pump for supplying the oxidant to the electricity generator, and a fixed frame that is provided on a lower frame and to which the pump is fixed. The pump is separated from the lower frame and is fixed to and combined with the fixed frame by the belt-shaped fixing member on the side surface of the fixing frame with a buffering member interposed. Therefore, it is possible to reduce the noise and vibration of the pump.
