一方、改質装置２内部の触媒を間接的に加温するバーナ２１にも同様の制御方式で燃料が供給される。改質装置２へは水素発生に必要なまた反応によって発生する一酸化炭素を低減するために純水や空気を供給し燃料電池４に必要な水素を作り出している。   On the other hand, the fuel is supplied to the burner 21 that indirectly heats the catalyst in the reformer 2 by the same control method. The reformer 2 is supplied with pure water or air to reduce the carbon monoxide required for hydrogen generation and generated by the reaction, thereby generating hydrogen necessary for the fuel cell 4.

次に、燃料電池４に供給される空気は制御装置７後方の下部に設定された空気供給ブロワー１０より吸引されて改質装置２上方の加湿器３で高温多湿の空気として燃料電池４に供給される。改質装置２と燃料電池４には純水が必要なためにイオン交換樹脂９で処理した水を水ポンプで供給している。燃料電池４に供給され残った空気は、貯湯回路の水を加温するために排熱回収装置１５に供給される。   Next, the air supplied to the fuel cell 4 is sucked from the air supply blower 10 set at the lower part behind the control device 7 and supplied to the fuel cell 4 as hot and humid air by the humidifier 3 above the reformer 2.

Therefore, booster pumps, purified air pumps, and other functional parts and components that do not have thermal characteristics such as booster pumps and purified air pumps are set at the bottom so that they are not affected by thermal convection in the housing. To improve durability.

また、摺動による振動を抑制するために、空気供給ブロワー１０、ブースターポンプ１４は筐体下部に設定し振動による騒音低減と人体の耳の位置とも距離をとることができ騒音に対する効果も出している。   In addition, in order to suppress vibration due to sliding, the air supply blower 10 and the booster pump 14 are set at the lower part of the housing to reduce noise due to vibration and to take a distance from the position of the ear of the human body. Yes.

さらに、バーナ２１を改質装置２の下部に設定したことによりバーナ２１の故障時に改質装置２を取り外さないで、バーナ単独で取り外すことが容易となるわけである。特にバーナ２１には燃焼検知となるフレームロッド、熱電対、点火電極などの燃焼熱の影響を受けて劣化する部品が設けられているために、バーナ単独で取り外しができる効果は極めて大きい。   Furthermore, by setting the burner 21 at the lower part of the reformer 2, it is easy to remove the burner alone without removing the reformer 2 when the burner 21 fails. In particular, the burner 21 is provided with parts that deteriorate due to the influence of combustion heat such as a flame rod, a thermocouple, and an ignition electrode for detecting combustion, so that the effect of being able to be removed by the burner alone is extremely great.

以上のように、本発明にかかる家庭用燃料電池コージェネシステム構成は前板、両側面及び天板を取り外すことですべての部品が容易に単独でメンテできるようにしたもので他の発電装置システムにも応用展開できるものである。   As described above, the home fuel cell cogeneration system configuration according to the present invention is such that all components can be easily maintained independently by removing the front plate, both side surfaces, and the top plate.
