    • A spacer disposed between first and second unit cells has a corrugated portion. The corrugated portion includes first and second protrusions alternating continuously and repeatedly in a vertical direction. The first protrusions protrude from a center in the thickness direction toward the first unit cell to faun clearances that function as cooling passages between the first protrusion and the second unit cell. The second protrusions protrude from the center in the thickness direction toward the second unit cell to form clearances that function as cooling passages between the second protrusions and the first unit cell. The spacer includes a straight portion extending in a direction crossing the cooling passages so as to prevent elongation of the corrugated portion in a direction perpendicular to the cooling passages.
    • 设置在第一和第二单元电池之间的间隔件具有波纹部分。 波纹部分包括沿垂直方向连续重复地交替的第一和第二突起。 第一突起从厚度方向的中心向第一单元电池突出,作为在第一突起和第二单元电池之间的冷却通道起作用的间隙。 第二突起从厚度方向的中心朝向第二单元电池突出,形成用作第二突起和第一单元电池之间的冷却通道的间隙。 间隔件包括沿与冷却通道交叉的方向延伸的直线部分,以防止波纹部分在与冷却通道垂直的方向上伸长。
