FUEL CELL STACK AND ITS FUEL CELL SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve the starting performance of an end cell from below the freezing point, thus improving the starting performance from below the freezing point as a fuel cell.

SOLUTION: The fuel cell stack comprises a stacked cell 2 stacking fuel cell units tightly and uniformly held from the stacking direction and an electric current extracting part 3 for extracting the electric current generated by the cell. A sealable fluid passage 3a for passing fluid is provided at least one side of the electric current extracting part 3 to reduce thermal capacity at the electric current extracting part.
