<P>PROBLEM TO BE SOLVED: To provide an impurity concentrating device for concentrating impurities included in hydrogen gas by utilizing an electrochemical hydrogen pump, in which a difference in concentration rate of impurities among cells is reduced when the cells constituting the electrochemical hydrogen pump are stacked in a plurality of numbers. <P>SOLUTION: The electrochemical hydrogen pump comprises a plurality of cells 22A, 22B, in which the cells 22B as a part of the plurality of cells 22A, 22B are low pressure loss cells having lower pressure loss in an anode flow passage than the cells 22A. The exits of anode flow passages of the cells 22A, 22B are connected to each other through an exit manifold 26. <P>COPYRIGHT: (C)2011,JPO&INPIT |
