〔参考例〕
〔その他の事項〕
上記実施の形態では、濃度センサ100はDMFCのアノードにメタノール水溶液が供給される直前の配管に取り付ける場合について説明したが、取り付け場所は、メタノール水溶液が供給される直前の配管に限定されるものではなく、バッファタンク232、DMFC本体240のマニホールドの部分、メタノール水溶液の排出側の配管などでも良い。また、配管の寸法は、濃度センサ100において光路長が5mmを超えないように設定することが望ましく、必要な流量を確保するために配管の内側寸法が2.5mm以上(光路長で5mm以上)となってしまうような場合には、厚み寸法が小さい流路を設けてその部分に配置することが望ましい。
