20080233447 | Fuel Cell and Fuel Cell Stack Comprising the Same - Even when a reaction gas flows into a gap formed between a gasket and a membrane electrode assembly, the flowing of the reaction gas to the outside without flowing through an electrode is prevented and thus a decrease in power generation efficiency is prevented. In order to allow the water vapor contained in the reaction gas that flows into an anode-side gap | 09-25-2008 |

20090162727 | FUEL CELL SEPARATOR AND FUEL CELL - A fuel cell separator and a fuel cell are provided that can improve uniformity in reaction gas flow rate and can prevent flooding due to excessive condensed water in passage grooves appropriately. A reaction gas passage region ( | 06-25-2009 |
20100068588 | MEMBRANE-MEMBRANE REINFORCING MEMBRANE ASSEMBLY, MEMBRANE-CATALYST LAYER ASSEMBLY, MEMBRANE-ELECTRODE ASSEMBLY, AND POLYMER ELECTROLYTE FUEL CELL - A membrane-membrane reinforcing member assembly includes: a polymer electrolyte membrane ( | 03-18-2010 |
20130011769 | FUEL CELL SEPARATOR AND FUEL CELL - A fuel cell separator having a turn portion of a serpentine-shaped reaction gas passage region. In the turn portion, a recessed portion is defined by an outer end of the turn portion and oblique boundaries between the recessed portion and a pair of passage groove group. In the turn portion, a plurality of protrusions, which vertically extend from a bottom face of the recessed portion and are arranged in an island form, are disposed such that one or more protrusions form a plurality of columns lined up and spaced apart from each other with a gap in a direction in which the outer end extends and one or more protrusions form a plurality of rows lined up and spaced apart from each other with a gap in a direction perpendicular to the direction in which the outer end extends. | 01-10-2013 |
