<P>PROBLEM TO BE SOLVED: To provide a fuel cell capable of appropriately releasing product gas generated at an anode catalyst layer and restraining rise of inner pressure due to generation of the product gas, and capable of restraining deterioration of a cell output by maintaining adhesiveness of an electromotive part and a collecting part. <P>SOLUTION: The fuel cell is provided with a support member 23 arranged between an anode conductive layer 17 and a vapor-liquid separation film 22 with a bottom part of its bottomed cylinder in contact with the anode conductive layer 17, equipped with an opening 24 at the bottom part leading evaporated fuel gas from a liquid fuel tank 21 to the anode catalyst layer 11, and with an exhaust port 25 opened at a side wall, and an inner pressure releasing member 26 exhausting product gas through the exhaust port 25 from a space inside the support member 23. The product gas generated at the anode catalyst layer 11 are intermittently exhausted outside and adhesiveness of the electromotive part and the collecting part is maintained to restrain deterioration of the cell output. <P>COPYRIGHT: (C)2007,JPO&INPIT |
