摘要： PROBLEM TO BE SOLVED: To provide a fuel cell stack structure in which, with no different conductive coat applied on a portion where cooling surfaces of metal separation plates contact each other, a smooth electric conductivity is assured by way of a contact part of two metal separation plates, resulting in reduction of a manufacturing cost of metal separation plates, for reduced unit cost of a fuel cell stack.SOLUTION: Cooling surfaces which face each other of metal separation plates forming a fuel cell stack by lamination are provided with a film removal part in which a passive film is removed for assuring electrical conductivity. The film removal part includes many fine roughs formed when the passive film is removed. On the contact surfaces formed by two film removal parts, contacting each other, of two metal separation plates adjoining each other, there are formed a contact part that keeps continuous electrical conductivity, because mutual roughs face each other, and contact is made so as to shield contacting to the air, resulting in suppression of formation of the passive film and a non-contact part where the passive film is formed as lapse of time by contact to the air because of no mutual contact.
