摘要： PROBLEM TO BE SOLVED: To provide a masking method of a base material with high mask dimensional accuracy with a simple masking. SOLUTION: In the masking method of a base material, a film 20 such as a seal coat for masking as an example is coated on a fuel cell separator base material 10 provided with a seal coat cut groove for masking 18 on a surface (S100). Next, the film 20 is made to have a cut along the seal coat cut groove for masking 18 with the use of a cutting tool 30 (S102). Then, by leaving a cutting film piece 20a on a non-treated part without applying a surface treatment of the fuel cell separator base material 10, a place without a need of coating on the fuel cell separator base material 10, that is a cutting film piece 20b on a surface treatment part, is separated (S104).

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a fuel cell component capable of correctly forming metal plated layers of a desired pattern on a surface of a base material of the fuel cell component; and to provide a fuel cell component where metal plated layers are correctly patterned on a surface of a base material. SOLUTION: A plate-like base material 1 provided with irregularity is prepared. Surfaces 2a, 3a and 3b of the recessed parts and the projecting parts of the base material 1 are hydrophobized by a hydrophobic substance to form hydrophobic layers 4. By photocatalyst lithography or photocatalyst scanning, the hydrophobic substance covering the top surfaces 2a of the projecting parts within the hydrophobized recessed parts and projecting parts is decomposed to become hydrophilic, whereby hydrophilic layers 5 are formed on the top surfaces 2a of the projecting parts. Finally, metal plated layers 6 are formed by selectively applying metal plating to the top surfaces 2a of the projecting parts which were made hydrophilic by immersing the base material 1 into a plating bath comprising a metal ion-containing aqueous solution.
