摘要： A first separator to which a resin film is joined beforehand is set in a cavity formed between a lower die and an upper die of an injection molding machine. At the time of die locking by moving the upper die toward the lower die, in the case where the total thickness of the resin film and the first separator is larger than a predetermined dimension, the resin film is pressed by the lower die or the upper die, and thus, the resin film is deformed by compression within its elastic deformation range.

摘要： A fuel cell is formed by stacking a membrane electrode assembly and separators alternately. Each of the separators includes first and second metal plates. A coolant flow field is formed between the first metal plate of the fuel cell and the second metal plate of the adjacent fuel cell. A folded section is provided around a coolant supply passage by folding the second metal plate. The folded section forms an inlet which enlarges the sectional area of an opening as a fluid passage between the coolant supply passage and the coolant flow field.

摘要： A method for treating the surface of a stainless steel product for a fuel cell containing, in wt %, 0.15% or less of C, 17 to 36% of Cr, 0.005 to 3.5% of B, which comprises the first step of forming in advance a passive film with an oxidizing acid on the surface of the stainless steel product, the second step of allowing an aqueous acid solution to corrode the passive film, to thereby project one or more of a M23C6 type carbide, a M23(C, B)6 type borocarbide and M2B type boride, which are inclusions having good electroconductivity, the third step of forming a passive coating film with an oxidizing acid on the surface of the steel product except that of the inclusion above projected, and the fourth step of washing with water and drying. The method of treatment allows, without the use of a method requiring a high cost such as gold plating, the improvement in the contact resistance of the stainless steel product for a fuel cell, which results in the retention of excellent characteristics of a stainless steel product over a long period of time.
