    摘要： A fuel cell includes a membrane electrode assembly, and a first and second separators for sandwiching the membrane electrode assembly. The first separator has an oxygen-containing gas flow passage for allowing an oxygen-containing gas in a serpentine pattern to flow horizontally back and forth, and flow downwardly. Partition areas are provided along the oxygen-containing gas flow passage in the serpentine pattern. The partition areas are formed by partially cutting out a gas diffusion layer. Insulating seals for preventing leakage of the oxygen-containing gas are provided in the partition areas.

    摘要： An oxygen-containing gas flow field is formed on a surface of a first metal separator. The oxygen-containing gas flow field is connected between an oxygen-containing gas supply passage and an oxygen-containing gas discharge passage. The oxygen-containing gas flow field comprises oxygen-containing gas flow grooves, and ends of the oxygen-containing gas flow grooves are extended outwardly beyond ends of electrode catalyst layer of a membrane electrode assembly, and connected to an inlet buffer and an outlet buffer. When the purging process is performed at the time of stopping operation of the fuel cell, the purging air supplied to the oxygen-containing gas flow field discharges water retained in the electrode catalyst layers from the ends to the outlet buffer.

    摘要： A fuel cell system includes a fuel cell and a supplying unit, which supplies reactive gases to the fuel cell. A control unit includes a power production effective area calculator calculates the areas of the electrodes available for power production as a power production effective area. A current density calculator which calculates a current density of the power production effective area calculated by the power production effective area calculator based on the total amount of power required by the fuel cell. A gas supply amount determiner determines the amount of reactive gas to be supplied to the fuel cell depending on the current density. A gas supply controller controls the supplying unit so as to supply the amount of reactive gas determined by the gas supply amount determiner to the fuel cell.
