Since the average pressure of the portion 13 rises and the gas reaches the portion where the pressure loss in the single sub-accommodating portion 13 is large, the total amount of hydrogen supplied to the outside from the gas outlet 18 increases.

Description
本発明の第1実施形態に係る2次電池型燃料電池システムの概略構成を図1に示す。本実施形態に係る2次電池型燃料電池システムは、燃料発生部材1と、燃料電池部2と、燃料電池部2を加熱するヒーター3と、燃料発生部材1を収容する収容部4と、燃料電池部2及びヒーター3を収容する容器5と、燃料発生部材1と燃料電池部2の間でガスを循環させるための配管6と、燃料発生部材1と燃料電池部2の燃料ガス流入側との間に設けられる排気バルブ7と、燃料発生部材1と燃料電池部2の間でガスを強制的に循環させるポンプ8と、断熱容器9と、燃料電池部2の空気極2Cに空気を供給するための配管10と、燃料電池部2の空気極2Cから空気を排出するための配管11と、システム全体を制御するシステムコントローラ12とを備えている。断熱容器9は、収容部4と、容器5と、配管6、10、及び11それぞれの一部とを収容している。また、燃料発生装置100は、燃料発生部材1と、収容部4と、排気バルブ7と、配管6との一部によって構成されている。

本発明の第2実施形態に係る2次電池型燃料電池システムの概略構成を図8に示す。本実施形態に係る2次電池型燃料電池システムは、第1実施形態に係る2次電池型燃料電池システムにガスを拡散する拡散部19を追加した構成である。拡散部19は、排気バルブ7と燃料発生装置100のガス流出口18との間に設けられる。これにより、排気バルブ7側から拡散部19に供給される水素量の変動を拡散部19によって吸収することができるので、燃料発生装置100のガス流出口18から燃料発生装置100の外部(燃料電池部2のガス流入側)に供給される水素量の変動を小さくすることができる(図9参照)。図9では、本実施形態での燃料発生装置100のガス流出口18から燃料発生装置100の外部(燃料電池部2のガス流入側)に供給される水素量を実線で示し、第1実施形態でのガス流出口18から燃料発生装置100の外部(燃料電池部2のガス流入側)に供給される水素量を破線で示している。図9から分かるように、排気バルブ7の周期的な開閉によってガス流出口から外部へ供給される水素量が変動しても(破線)、燃料電池部2のガス流入側に供給される水素量の変動が抑えられ(実線)、燃料電池部2の発電量を安定させることができる。
本発明の第3実施形態に係る2次電池型燃料電池システムの概略構成は、第1実施形態に係る2次電池型燃料電池システムの概略構成と同じく図1に示す構成である。また、本実施形態における燃料発生装置100の構成も第1実施形態における燃料発生装置100の構成と同じく図2に示す構成である。
本発明の第4実施形態に係る2次電池型燃料電池システムの概略構成は、第1実施形態に係る2次電池型燃料電池システムの概略構成と同じく図1に示す構成である。ただし、本実施形態に係る燃料発生装置100の構成は第1実施形態における燃料発生装置100の構成と異なり図13に示す構成である。
本発明の第5実施形態に係る2次電池型燃料電池システムの概略構成は、収容部4を3つ備える点で第1実施形態に係る2次電池型燃料電池システムの概略構成と大きく異なっているが、燃料発生装置100以外の部分は第1実施形態に係る2次電池型燃料電池システムと同じく図1に示す構成である。尚、収容部の数は2つ以下または4つ以上であっても構わない。
上述した各実施形態においては、燃料電池部2の電解質膜2Aとして固体酸化物電解質を用いて、発電の際に燃料極2B側で水を発生させるようにする。この構成によれば、燃料発生部材1が設けられた側で水を発生するため、装置の簡素化や小型化に有利である。一方、特開2009-99491号公報に開示された燃料電池のように、燃料電池部2の電解質膜2Aとして水素イオンを通す固体高分子電解質を用いることも可能である。但し、この場合には、発電の際に燃料電池部2の酸化剤極である空気極2C側で水が発生されることになるため、この水を燃料発生部材1に伝搬する流路を設ければよい。また、上述した各実施形態では、1つの燃料電池部2が発電も水の電気分解も行っているが、燃料電池(例えば発電専用の固体酸化物燃料電池)と水の電気分解器(例えば水の電気分解専用の固体酸化物燃料電池)が燃料発生部材1に対してガス流路上並列に接続される構成にしてもよい。
