流入ガス条件が高温運転 PEFC 単セル内熱・物質移動現象に及ぼす影響

抄録

In-plane temperature distribution of gas separator at anode and cathode of single cell of PEFC generated at high temperature was measured by thermograph. The effects of initial operation temperature of cell, relative humidity and flow rate of supply gas as well as cathode gas type on the in-plane temperature distribution were investigated. As a result, the temperature increased along gas flow through gas channel from the inlet to the middle, and then decreased. The impact of relative humidity difference of supply gas between the anode and the cathode on the temperature distribution was not confirmed under the investigated conditions.
