INSPECTION METHOD AND MANUFACTURING METHOD OF FUEL CELL

PROBLEM TO BE SOLVED: To achieve an inspection of an output in a transient condition.SOLUTION: A current density is increased from a specified value J1 to a maximum value J2 with a rise rate of 0.5 A/(cmsec) (Step S120). Five minutes after the rise is completed, a cell voltage V3 is obtained (Step S...

Summary:PROBLEM TO BE SOLVED: To achieve an inspection of an output in a transient condition.SOLUTION: A current density is increased from a specified value J1 to a maximum value J2 with a rise rate of 0.5 A/(cmsec) (Step S120). Five minutes after the rise is completed, a cell voltage V3 is obtained (Step S130). When the cell voltage V3 is low (Step S150, NO), it is determined that cation contamination occurs (Step S160).SELECTED DRAWING: Figure 3 【課題】過渡的な条件における出力の検査を実現すること。【解決手段】０．５Ａ／（ｃｍ2・ｓｅｃ）の上昇速度で、電流密度を所定値Ｊ１から最大値Ｊ２まで上昇させる（ステップＳ１２０）。前記上昇が完了してから５秒後のセル電圧Ｖ３を取得する（ステップＳ１３０）。セル電圧Ｖ３が低い場合（ステップＳ１５０、ＮＯ）、カチオン汚染が発生していると判定する（ステップＳ１６０）。【選択図】図３
