Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a fuel battery system capable of measuring a hydrogen concentration in an anode circulating gas under an environment of high temperature and high humidity.SOLUTION: A fuel battery system 1 includes a fuel battery 2, a controller thereof, a first hydrogen detection film 22a which is configured to contain a metal oxide film and is provided in a flow path for circulating gas exhausted from an anode electrode 2a of the fuel battery 2 to an anode return path 15b, and a transmitted light intensity detector for detecting the transmitted light intensity of the first hydrogen detection film 22a. When the fuel battery 2 is operated, the controller measures the hydrogen concentration of the circulating gas exhausted from the anode electrode 2a to the anode return path 15b based on the transmitted light intensity detected by the transmitted light intensity detector.SELECTED DRAWING: Figure 1
【課題】 高温、高湿の環境下で、アノード循環ガス中の水素濃度を測定することができる燃料電池システムを提供する。【解決手段】 燃料電池システム1は、燃料電池2と、その制御部と、金属酸化膜を含んで構成され、燃料電池2のアノード電極2aからアノード戻り路15bに排出される循環ガスの流路に設けられた第1水素検知膜22aと、第1水素検知膜22aの透過光強度を検出する透過光強度検出部と、を備える。制御部は、燃料電池2を作動させているとき、透過光強度検出部により検出される透過光強度に基づいて、アノード電極2aからアノード戻り路15bに排出される循環ガスの水素濃度を測定する。【選択図】 図1 |
