Abstract
【解決手段】 入口温度センサ5は、スタック入口の冷却水温度を検出して、コントローラ21へ出力する。コントローラ21は、冷却水ポンプ3を制御すると共に、入口温度センサ5が検出したスタック入口の冷却水温度に応じて、燃料電池スタック1から負荷17へ供給する電力または電流を制限する。
【選択図】 図1
Description
許容温度差=冷却水出口許容最大温度−冷却水入口温度 …(1)
ここで、スタック入口冷却水温度TwiがTL〔℃〕以下であれば、スタック取り出し電流Io を最大電流Amax まで取り出しても、スタック出口冷却水温度は許容温度以下であり、取り出し電流を制限する必要はない。
スタック入口出口冷却水温度差ΔT=スタック放熱量Q/冷却水流量Fw …(2)
本実施例では、図7のS13におけるスタック入口出口冷却水温度差の予測を図8、図10の特性を記憶したマップを参照することによって、冷却水流量がばらついた場合でも、精度よく取り出し電流に制限をかけることが可能となった。
