AI Technical Summary

Technical Problem

In electrochemical hydrogen pumps, thermal variations between the outer and inner portions of the electrolyte membrane cause deformation due to differences in thermal expansion, which can be exacerbated by heat generation during operation.

Method used

A temperature control mechanism is implemented using a temperature adjustment member with a first and second flow path component, allowing refrigerant or heat transfer medium to circulate between the membrane electrode assembly and separators, thereby controlling temperature uniformity and suppressing deformation.

Benefits of technology

The temperature adjustment member effectively suppresses thermal variations, preventing electrolyte membrane deformation and ensuring consistent operation by maintaining uniform temperature distribution across the membrane.

Abstract

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
