FUEL CELL SEPARATOR AND FUEL CELL PROVIDED WITH SAME

摘要

A fuel cell separator of the present invention is formed such that a first reaction gas flowpath (131) has a first portion (41) and a second portion (51) located upstream of the first portion (41), and the first portion (41) is closest to an upstream end at a portion between the second portion (51) of the first reaction gas flowpath (131) and a downstream end, the second portion (51) is closest to the downstream end at a portion between the upstream end of the first reaction gas flowpath (131) and the first portion (41), second reaction gas flowpaths (132, 133) are not interposed between the first portion (41) and the upstream end, and the second reaction gas flowpaths (132, 133) are interposed between the second portion (51) and the downstream end, and the first reaction gas flowpath (131) is formed so as to communicate with at least one reaction gas flowpath (hereafter, a specific flowpath) of the second reaction gas flowpaths (132, 133) at a portion between the first portion (41) and the downstream end (hereafter, a specific portion).
