To improve abnormality estimation accuracy of a fuel cell.SOLUTION: A fuel cell abnormality estimation device according to an aspect of an embodiment estimates whether the fuel cell mounted on a vehicle is abnormal or not. The fuel cell abnormality estimation device comprises an acceleration information acquisition unit, an abnormality estimation unit, and an abnormality signal output unit. The acceleration information acquisition unit acquires the acceleration information indicating the acceleration detected by the acceleration sensor used when determining whether or not the deployment of the airbag mounted on the vehicle is required. The abnormality estimation unit estimates whether or not a deviation is generated between a plurality of single cells contained in the fuel cell according to each of comparison results between the acceleration information and a plurality of threshold values. The abnormality signal output unit outputs a fuel cell abnormality signal when the abnormality estimation unit estimates that a deviation was generated between the plurality of single cells.SELECTED DRAWING: Figure 4

    【課題】燃料電池の異常推定精度を向上させること。【解決手段】実施形態の一態様に係る燃料電池異常推定装置は、車両に搭載された燃料電池の異常の有無を推定する燃料電池異常推定装置であって、加速度情報取得部と、異常推定部と、異常信号出力部とを有する。加速度情報取得部は、車両に搭載されたエアバッグの展開の要否を判定するときに使用される加速度センサが検出した加速度を示す加速度情報を取得する。異常推定部は、加速度情報と複数の閾値との各比較結果に応じて、燃料電池に含まれる複数の単セルの間にずれが生じたか否かを推定する。異常信号出力部は、異常推定部によって複数の単セルの間にずれが生じたと推定されたときに、燃料電池異常信号を出力する。【選択図】図4
