| Zusammenfassung: | To provide an inspection method for a fuel battery cell that can more accurately evaluate the amount of gas leaked from the fuel battery cell.SOLUTION: An inspection method of a fuel battery cell 10 having a membrane electrode assembly 14 in which an electrolyte membrane 11 is sandwiched between a pair of electrodes 12 includes leak inspection steps ST2 and ST3 of measuring a measured value including the amount of gas permeation in an electrolyte membrane 11, and a pressure loss inspection step ST1 of passing dry gas through the fuel battery cell 10 and measuring the pressure loss of the gas, and the step immediately before the leak inspection steps ST2 and ST3 is the pressure loss inspection step ST1.SELECTED DRAWING: Figure 4
【課題】燃料電池セルのガス漏れ量をより正確に評価することができる燃料電池セルの検査方法を提供する。【解決手段】検査方法は、電解質膜１１を一対の電極１２で挟んだ膜電極接合体１４を備えた燃料電池セル１０を検査する方法であり、電解質膜１１におけるガス透過量を含んだ測定値を測定するリーク検査工程ＳＴ２，ＳＴ３と、燃料電池セル１０に乾いた気体を流して該気体の圧力損失を測定する圧損検査工程ＳＴ１と、を含み、リーク検査工程ＳＴ２，ＳＴ３の直前の工程が、圧損検査工程ＳＴ１であることを特徴としている。【選択図】図４ |
