<P>PROBLEM TO BE SOLVED: To inhibit decrease of moisture content owing to low partial water vapor pressure of oxidation gas, in a polymer electrolyte fuel cell. <P>SOLUTION: The fuel cell 10 is provided with a plate-shape single cell 40 and a rotation shaft 20, as a center of rotation of the single cell 40, provided through the single cell 40 vertical to a surface direction. The single cell 40 is provided with an electrolyte membrane 41 of a polymer electrolyte, catalytic electrode layers formed on both surfaces of the electrolyte membrane 41, an oxidation gas route in the single cell, formed on a catalytic electrode layer, for introducing the oxidation gas to neighbourhood of the rotation shaft 20 from an outer circumference part side of the electrolyte membrane 41 and a fuel gas route in the single cell formed on the other catalytic electrode layer to introduce the fuel gas having a shape allowing water to move from the rotation shaft 20 side to the outer circumference part side of the electrolyte membrane 41 when the single cell 40 rotates around the rotation shaft 20. <P>COPYRIGHT: (C)2008,JPO&INPIT |
