図1に、本発明の第1実施形態に係る燃料電池システム1の概略構成を示す。なお、本実施形態に係る燃料電池システム1は、燃料電池自動車の電源システムとして開発されたものである。より具体的には、燃料電池システム1は、燃料電池自動車の、DC−DCコンバータ、インバータ、バッテリ、車両用モータ等からなる部分(図1では、“負荷”)に電力を供給するためのシステムとして開発されたものとなっている。
本発明の第2実施形態に係る燃料電池システムは、上記したものとは若干異なる制御がECU30によって行われるように第1実施形態に係る燃料電池システム1を改良したシステムである。このため、以下では、第1実施形態の燃料電池システム1の説明時に用いたものと同じ符号を用いて、第2実施形態に係る燃料電池システム1内のECU30の制御動作のみを説明することにする。
上記した各実施形態に係る燃料電池システム1は、各種の変形を行うことが出来る。例えば、各実施形態に係る燃料電池システム1は、主燃料、副燃料として、それぞれ、エタノール、エチレングリコールを用いたものであったが、各燃料として、他の物質が使用されたものに、燃料電池システム1を変形することが出来る。
