    摘要： A fuel cell system including a fuel cell, a gas-liquid separator, a tank, an outlet pipe, and an inlet pipe is disclosed. The gas-liquid separator separates off-gas discharged from the fuel cell into water and gas. The tank is capable of containing water separated by the gas-liquid separator. The outlet pipe discharges gas, which is separated by the gas-liquid separator, from the gas-liquid separator. The outlet pipe has a venturi. The inlet pipe draws the water contained in the tank into the venturi. The water contained in the tank is drawn through the inlet pipe into the venturi to be atomized and discharged as atomized water from the outlet pipe.

    摘要： A fuel cell apparatus is formed by connecting four stacks via a supply/discharge box. A cooling water supply opening and a cooling water discharge opening are short-circuited by a cable so as to eliminate the electric potential difference therebetween. To avoid hindrance of gas flow due to water droplets, a drain port for discharging water droplets is provided near a fuel gas discharge opening of the supply/discharge box. Each stack is formed by clamping end plates disposed on opposite ends of stacked cells through the use of upper and lower tension plates. The thus-formed fuel cell apparatus is housed in an outer case that has a sealed construction for preventing penetration of foreign substances. Thus, the apparatus achieves a size reduction and an improvement in practicality.

    摘要： The object of the present invention is to provide a fuel cell stack with improved corrosion resistance of metal separators and reduced cost. To attain this object, the fuel cell stack according to the present invention has a cell stack constituted by stacking a prescribed number of unit cells obtained by sandwiching both surfaces of an electrolyte membrane between an anode and a cathode and sandwiching the outer sides thereof with a pair of metal separators, wherein the metal separator positioned on the plus side of the cell stack is subjected to surface treatment providing for relatively higher corrosion resistance than the metal separator positioned on the minus side of the cell stack. Cost reduction can be realized, while maintaining corrosion resistance comparable with that obtained in the case when all the separators are subjected to the anticorrosive surface treatment to the same degree.
