Electrochemical reaction module

Abstract

This suppresses the temperature drop in the electrochemical reaction cell stack. [Solution] The electrochemical reaction module comprises an electrochemical reaction cell stack, an auxiliary device, a fuel gas supply passage through which fuel gas supplied from the auxiliary device to the electrochemical reaction cell stack passes, a fuel gas discharge passage through which fuel gas discharged from the electrochemical reaction cell stack to the auxiliary device passes, an oxidant gas supply passage through which oxidant gas supplied from the auxiliary device to the electrochemical reaction cell stack passes, and an oxidant gas discharge passage through which oxidant gas discharged from the electrochemical reaction cell stack to the auxiliary device passes. The fuel gas supply passage, fuel gas discharge passage, oxidant gas supply passage, and oxidant gas discharge passage each have a portion arranged along the electrochemical reaction cell stack, and when the lengths of the portions of the oxidant gas supply passage and the oxidant gas discharge passage arranged along the electrochemical reaction cell stack are denoted as LO1 and LO2, LO1
