<P>PROBLEM TO BE SOLVED: To provide a fuel cell system improved in hydrogen utilization rate, effective output and energy density. <P>SOLUTION: A tube structure 40 and a check valve 33 are connected to a connection 32 of a hydrogen supply 1 and an anode chamber 23 through a check valve 34. The other end of the check valve 33 is connected to the anode chamber 23 through a connection 31. When the internal pressure of the hydrogen supply 1 is high, hydrogen flowing from the hydrogen supply 1 to the anode chamber 23 flows in the tube structure 40. When the internal pressure of the hydrogen supply 1 becomes low, the tube structure 40 supplies hydrogen, thus repeating increase and decrease in the internal pressure of the fuel cell system in its internal pressure. <P>COPYRIGHT: (C)2007,JPO&INPIT |
