ELECTROCHEMICAL HYDROGEN PUMP

To provide an electrochemical hydrogen pump that can suppress deformation of a polymer electrolyte to the anode side because of the difference of thermal expansion in the polymer electrolyte due to thermal variations in an electrochemical cell.SOLUTION: An electrochemical cell 18 of an electrochemical hydrogen pump 10 comprises a temperature regulation member 72. The temperature regulation member 72 comprises a first flow path component 84 having a first flow path 104 and a second flow path component 86 having a second flow path 118 in communication with the first flow path 104. The first flow path component 84 is arranged between a polymer electrolyte/electrode structure 66 and the second flow path component 86.SELECTED DRAWING: Figure 5 【課題】電気化学セル内での熱ばらつきにより電解質膜に熱膨張差が生じ、電解質膜がアノード側に変形することを抑制する、電気化学式水素ポンプを提供する。【解決手段】電気化学式水素ポンプ１０の電気化学セル１８は、温度調節部材７２を備える。温度調節部材７２は、第１流路１０４を有した第１流路構成部材８４と、第１流路１０４に連通する第２流路１１８を有した第２流路構成部材８６と、を備える。第１流路構成部材８４は、電解質膜・電極構造体６６と第２流路構成部材８６との間に配置される。【選択図】図５
