<P>PROBLEM TO BE SOLVED: To provide a fuel cell power generating device which removes impurities contained in an oxidizer gas or the air, suppresses the degradation due to the impurities, and improves the durability. <P>SOLUTION: The fuel cell power generating device is equipped with a fuel cell 5 comprising an alkaline impurity removing filter 9 to remove alkaline impurities, an acidic impurity removing filter 11 to remove acidic impurities, a filter 12 to remove dust, a case 13 to enclose these, an electrolyte 1, a pair of electrodes 21, 22, and a pair of separators 41, 42. By removing alkaline impurities such as ammonia and trimethylamine, acidic impurities such as hydrogen sulfide, sulfur dioxide, nitrogen dioxide, hydrogen chloride and hydrogen fluoride, and particulate impurities such as dust, which all may possibly be present in the air, and preventing these impurities from mingling in the fuel cell 5; the poisoning of a catalyst by these impurities and the decrease in the ion conduction are prevented, and thereby the decrease in the cell voltage is suppressed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
