PROBLEM TO BE SOLVED: To provide a bipolar electrode plate of a fuel cell with its simple structure at low cost by integrally and structurally forming the bipolar electrode plate by only one comprehensive iron plate body. SOLUTION: A bipolar electrode plate provided in a fuel cell laminate, an anode and a cathode of adjacent fuel cells being separated and contacted is constituted by only one comprehensive iron plate body 400. This comprehensive iron plate body is oriented to an anode 1 and forms a plenty of first protrusions 410 for the anode 1. The plate body is oriented to a cathode 2 and has contact faces for the cathode 2. The plate body has a plenty of the first protrusions 410 spaced each other and disposed by a cavity interval. Further, the plate body has a plenty of second protrusions 420 disposed each other with intervals by the cavity interval. The cavity interval between the second protrusions 420 forms a flow path of a flow gas B flowing a side 1 of the bipolar plate. The iron plate body 400 is formed of a specific steel, and only anode side is plated with nickel. |
