 note = {PEFC環境におけるステンレス鋼セパレータからの鉄の溶出挙動を調査するために，SUS304をpH 3.0および3.2の硫酸酸性溶液中で100 h定電位分極した際の溶出金属量をICP-MSで定量した．pH 3.2の場合はアノード酸化された鉄のうち90％以上が腐食生成物としてステンレス鋼表面に留まった．一方でpH 3.0では約75％が溶出することが明らかとなった．このことはセパレータのおかれる環境のpHが3.0を下回った場合に，鉄の溶出によるMEAの汚染が強く懸念されること，一方pH 3.2以上では析出した酸化鉄によるICRの増加が懸念されることを示唆している．, In order to investigate the effect of pH on the dissolution behavior of iron from stainless steel bipolar plates for PEFC, type 304 stainless steel was polarized in the sulfuric acid solutions of pHs 3.0 and 3.2 for 100 h at 0.6 V （vs. Ag/AgCl）, and the amount of dissolved metallic ions was determined by ICP-MS. In the solution of pH 3.2, more than 90％ of the anodized iron was deposited on the stainless steel surface as corrosion products, whereas about 75％ of the anodized iron was dissolved in the solution of pH 3.0. These results suggest that the contamination of MEA by the dissolved iron is more concerned when the pH of the environment becomes lower than 3.0, while the increase in interfacial contact resistance is rather concerned when the pH is higher than 3.2.},
