Description
上記従来の課題を解決するために、本発明に係る水素生成装置は、原料が供給されて水素を含む改質ガスを生成する改質部と、前記改質部から供給される前記改質ガス中の一酸化炭素をシフト触媒の存在下で進行するシフト反応により除去する変成部と、前記シフト触媒の温度を直接的又は間接的に検出する温度検出部とを備える水素生成装置であって、前記改質部に供給される前記原料の供給量に応じて予め設定された前記温度検出部により検出される前記シフト触媒の基準温度を前記水素生成装置の起動回数及び停止回数の少なくとも何れかの回数の増加に応じてより高い温度に変更し、前記温度検出部により検出される前記シフト触媒の温度が前記基準温度以上に到達した時点で前記基準温度に対応した供給量にまで前記原料の供給量を増加させる（請求項１）。 In order to solve the above-described conventional problems, a hydrogen generator according to the present invention includes a reforming unit that supplies a raw material to generate a reformed gas containing hydrogen, and the reformed gas that is supplied from the reforming unit. A hydrogen generator comprising a shift unit that removes carbon monoxide by a shift reaction that proceeds in the presence of a shift catalyst, and a temperature detection unit that directly or indirectly detects the temperature of the shift catalyst, The reference temperature of the shift catalyst detected by the temperature detection unit set in advance according to the supply amount of the raw material supplied to the reforming unit is set to at least one of the number of startups and the number of stops of the hydrogen generator As the number of times increases, the temperature is changed to a higher temperature, and when the temperature of the shift catalyst detected by the temperature detection unit reaches or exceeds the reference temperature, the raw material is supplied to the supply amount corresponding to the reference temperature. amount Ru is increased (claim 1).
かかる構成とすると、水素生成装置の起動回数及び停止回数の少なくとも何れかの回数の増加に応じて基準温度をより高い温度に変更するので、性能劣化に応じてシフト触媒の触媒活性を調整することができ、これによりシフト触媒が劣化した場合であっても、一酸化炭素が十分に除去された良質の改質ガスを燃料電池に供給することが可能になる。又、かかる構成とすると、シフト触媒の温度が基準温度以上に到達した時点で改質部への原料の供給量が増加されるので、一酸化炭素が十分に除去された良質の改質ガスを燃料電池に供給することが可能になる。 With such a configuration, the reference temperature is changed to a higher temperature in accordance with an increase in at least one of the number of startups and the number of shutdowns of the hydrogen generator, so that the catalytic activity of the shift catalyst can be adjusted according to performance degradation. Thus, even when the shift catalyst is deteriorated, it is possible to supply a high quality reformed gas from which carbon monoxide has been sufficiently removed to the fuel cell. Also, with such a configuration, when the temperature of the shift catalyst reaches the reference temperature or higher, the amount of raw material supplied to the reforming section is increased, so that a high quality reformed gas from which carbon monoxide has been sufficiently removed can be obtained. The fuel cell can be supplied.
又、上記の場合、前記温度検出部の出力に基づいて前記シフト触媒の温度を制御するための加熱手段を更に備え、前記加熱手段から供給される熱により前記シフト触媒が加熱される（請求項３）。
Further, in the above case, a heating means for controlling the temperature of the shift catalyst based on the output of the temperature detection unit is further provided, and the shift catalyst is heated by the heat supplied from the heating means (claim). 3).
