摘要： A first positioning hole is formed in a first positioning portion of a separator member, which is a fuel cell separator member forming a fuel cell stack. The first positioning portion includes a reinforcing rib and a joint portion. The reinforcing rib extends linearly outside the first positioning hole and protrudes from each of a first metal separator and a second metal separator. The joint portion is located between the reinforcing rib and the first positioning hole, and the first metal separator and the second metal separator are joined together at the joint portion.
