Embodiment Construction
[0058] Such as figure 1 and figure 2 As shown, the fuel cell stack 10 according to the first embodiment of the present invention is formed by stacking a plurality of fuel cells 12 in the horizontal direction (direction of arrow A) or vertical direction (direction of arrow C).
[0059] In the fuel cell 12 , an electrolyte membrane-electrode structure (electrolyte-electrode structure) 14 is sandwiched between first metal separators 16 and second metal separators 18 . The first metal separator 16 and the second metal separator 18 are made of, for example, a steel plate, a stainless steel plate, an aluminum plate, or a plated steel plate, and are punched into a corrugated plate shape to form a flow path described later.
[0060] Such as figure 1 As shown, in the arrow B direction of the fuel cell 12 ( figure 1 , in the horizontal direction) along the arrow C direction (vertical direction) along the arrow C direction (vertical direction) arranged in a stacking direction, that ...
