<P>PROBLEM TO BE SOLVED: To enable use of a closed system by eliminating exhaust gas in a fuel cell system, and improve efficiency by generating power with recovered hydrogen and oxygen. <P>SOLUTION: This is equipped with a hydrogen supply passage 111 to supply hydrogen to the fuel cell 100, an un-reacted hydrogen exhaust passage 112 to exhaust un-reacted hydrogen in the fuel cell, an oxygen supply passage 121 to supply oxygen to the fuel cell, an oxygen circulation passage 125 to return the un-reacted oxygen in the fuel cell, an oxygen purge passage 126 to purge a part of oxygen in the oxygen circulation passage, an oxygen buffer tank 145 installed at the oxygen purge passage, a hydrogen-recovery fuel cell 150 to carry out power generation with hydrogen in the un-reacted hydrogen exhaust passage and oxygen in the oxygen purge passage, an un-recovered hydrogen gas circulation passage 132 to return the un-recovered hydrogen gas of the hydrogen-recovery fuel cell, an adsorption filter 133 to remove hydrogen gas impurities, an un-recovered oxygen gas circulation passage 142 to return the un-recovered oxygen gas of the hydrogen-recovery fuel cell, and an adsorption filter 143 to remove oxygen gas impurities. <P>COPYRIGHT: (C)2009,JPO&INPIT |
