FUEL CELL, FUEL CELL-EQUIPPED VEHICLE, AND MEMBRANE ELECTRODE UNIT

摘要

The invention provides a fuel cell, which includes: an electrolyte (23); an anode (22) that is placed on one side of the electrolyte (23) and has a fuel gas consumption surface on which fuel gas is consumed; a cathode (24) that is placed on the other side of the electrolyte (23); and a fuel gas passage (225n) having a first passage (14h) for distributing fuel gas to previously set regions on the fuel gas supply surface, a second passage (22) for supplying the distributed fuel gas to the regions, and a fuel gas supply portion (21n) for supplying fuel gas from the first passage (14h) to the second pas-sage (22). The fuel cell consumes most of the supplied fuel gas in the regions on the fuel gas consumption surface. A fuel gas passage (225n) has a fuel gas leakage suppression portion (14hg, 52n) for suppressing leakage of fuel gas between the first passage (14h) and the second passage (22).
