To provide a gas pump making stable power generation possible by efficiently supplying gas of a flow rate of small pulsation in a fuel cell system.
Opposite direction magnetic force alternately acts to a permanent magnet 28 by an electromagnet 29 to reciprocate a driving rod 27, a moving body 25 fixed to both ends of the driving rod is moved in front and the rear to alternately increase and decrease the volume of a pair of pump chambers 24. When the volume of one pump chamber is increased and gas flows in the pump chamber through an admission valve from a suction passage, the volume of the other pump chamber is decreased, gas is discharged to a discharge passage 36, through a delivery valve 33, and since this action is continuously repeated, gas is continuously supplied from a pair of pump chambers to the discharge passage, and joined in the discharge passage to relieve flow rate variation.
